remove the grill to gain access

what i do is go to a good salvage yard and fine one the same as my and replace the hole thing take it to a locksmith first and have it rekey so my keys are all the same try this website to see if there is a good salvage yard near you try this website it www.junkyarddog.com to find one close to you.

Check the transmission mount and you the clutch packs may be worn, Best thing to do at this point is to service the transmission and add some additives to get a bit more out of your clutch pack before you replace the transmission. Just wear and tear my friend, good luck and hope this helps, you can also have them replace the servo's with Corvette servo's, they run around $45,00 and you don't even have to drop the transmission pan to swap them out. The servo's will give you a better fluid pressure to the clutch packs.

look behind the grill, not easy to see, and see where the cable hooks up. Take a screw driver and pry the latch in the direction the the cable would move it. I had to do this on a 1992 s10

I don't have a diagram, But I have taken tons of these apart. Is there something I can help with?

3/8 hex/allen for the caliper guide pins.

Check the brake switch at the top of the brake pedal arm.

If you have power either you are missing the ground somewhere or the door lock actuators are bad

bad bearings will do strange things, check your front end for play If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_4c166ba81493f541

Sounds like possibly the blend door is broken inside the heater box, I would double check and make sure the coolant level is full, if it is I would take the actuator off on the blend door and try and move it by hand and see if it changes

Need more information... Can you hear the compressor clutch kick in when AC is on? Have you checked freon pressure? Oreillys should sell a gauge that attaches to can of freon

The parking brake for an older truck is a cable system.. they do become stretched and MAY need replacing....make sure the emergency brake is OFF....make sure the rear brakes are adjusted as well (tight) as they can be..(takes the "slack" out as much as possible so when you apply the E Brake you are not just taking up "slack"))....Its GREAT to have a buddy to help with this... .. Start at the brake "pedal" in the cab.. make sure the cable is routed correctly and secure at all the connections, .. and the pedal travel is sufficient to move the cables located.under the truck,,if I remember correctly there is one cable coming from the cab to a splitter that branches off to each wheel.. check all the connections and the actuators in the backing plate to see if they are working...its just a matter of taking out.... "the slack".. Good luck, ...please mark as helpful..

you can remove what ever is preventing you from getting the pipe and slave cylinder to line up an start in the thread the fitting should go all the way i finger tight and only use a spanner for the last bit

Check the fuse panel

Do an exhaust pressure test on the tail pipe sounds like the cat or muffler maybe plugging up. If it is then the engine won't allow engine to pull fuel into the cylinders and fire.

Then the wiring to the pump is shorted inline or the connector to the pump has burned terminal which causes an over current issue and can blow the fuse. You did change the fuel pump connector correct?

check your heater core Chevy is bad for that if water pump goes out heater core will to hoses go from motor threw fire wall leak will be coming out of fire wall between hoses

Chevy Cavalier Air Conditioning Clutch replacement
Just finished it. I am an novice. Use safety glasses, Dust and dirt will get in you eyes even with the protection.

Disassembly:
Pop and raise the hood.
Loosen the left front lug nuts. Jack up car the higher the better. Install jack stands! Remove left front wheel. Place wheel under car to act as a last chance stand in case your jack stands fail.
Using 9/32 nut driver remove screws that hold plastic shielding to the inner fender well so as to expose AC compressor.
You will also have to pullout the Plastic snap things with needle nose pliers so get the plastic covers away from you work area ( I didn’t remove ALL of the plastic completely, just enough to swing it out of the way. There is a box of electrical stuff right there (wires) but the screws that were holding it to the inside wheel well had rusted away so it moved with the plastic when pulled out and away.
Pull down on the belt tensioner to loosen the serpentine belt (its hard to do) and slip the belt off of the AC compressor pulley.
Disconnect the AC Electromagnetic clutch power wires, (it is facing the front of the vehicle) the connector has little "Wings" that must be "Slightly pried apart" in order to remove the plastic connector from the compressor.
Using a 1/2" socket remove the nut that is in the center of the clutch assembly (to remove- turn it counter clockwise), I used a pry bar against the upper control arm and a notch in the Outer clutch plate to hold the A/C outer clutch plate from turning as I turned and removed the nut.

IMPORTANT! This nut that you are removing is threaded on to the A/C compressor shaft. DO NOT DAMAGE the A/C compressor shaft or the threads on which the nut is threaded.

NOTE: Be aware there is a "KEY", a small rectangular piece of metal that is on the shaft of the compressor, it will either stick to the outer clutch components or to the A/C shaft. This key is what transfers the belt energy onto the Compressor shaft (do not misplace).

This outer clutch plate is to pull straight out to leave exposed the inner clutch plate.
I suppose a few screwdrivers or chisels may do the trick but this part must come off of the compressor to get to the important next part.
I used a TIE ROD End Puller to slide the outer clutch plate out and off of the compressor shaft.
By driving the tie rod tool between the outer and inner clutch surfaces the outer clutch slid from the compressor shaft. Any wedge type device should be able to do this.

IMPORTANT! There is a "Hidden" C clip (snap ring) behind the outer clutch plate! ( I did not know this until I broke the end of the compressor nose off by pulling the pulley off with a pulley puller). Please read on...

The "C" Clip. This clip uses snap ring pliers to be removed. This clip holds the inner clutch assembly onto the compressor. The snap ring is holding onto the "Nose" of the compressor.
This clip is now "closed" you must "open" the clip so that it can be pulled off of the nose of the A/C compressor.
I used "Snap Ring Pliers" but I suppose a "Ground-to-a-point" Needle Nose Pliers "May" work.
Once you have removed the retaining ring the next thing that comes off is the inner assembly.
I used a pulley puller to remove the pulley but the Auto parts store in which I purchased the new A/C clutch would let me "Borrow" the AC clutch puller tool. This is the way to go if you are doing this on a budget. The A/C clutch puller grasps the A/C pulley on two sides and pushes against the compressor shaft, thereby sliding the inner clutch assembly EVENLY out and away from the A/C compressor "Nose".

IMPORTANT! DO NOT DAMAGE the A/C compressor shaft you will not be able to repair it if you do!
With the inner clutch assembly removed, the last thing to come off is the fragile A/C electromagnet, If you need to replace it.

The "Electromagnet":
This is a plastic coated coil of fine wire that electrical current flows through when the A/C is turned "ON" inside the car. When the current flows through it, it creates a strong magnetic field and this magnetic field pulls the outer A/C clutch parts into contact with the inner A/C clutch parts until they touch. This force is strong enough to transfer the spinning energy of the serpentine belt through the clutch onto the compressor shaft (by way of the "Key") and turn the insides of the A/C compressor to compress the liquid coolant and send it on its way through the A/C hoses.

This electromagnet came with the new clutch assembly I purchased so I changed mine. (I broke the connector off with a screwdriver earlier so I'm glad I got a new one).

NOTE: Notice where the magnet electrical connection is facing (forward- you'll need to remember).
I used several screwdrivers to evenly force the "Magnet" off of the Compressor "Nose".
It must move about 2" before it falls off, so I ended up using some "wedge like" chisels and screwdrivers to force it off by driving them between the A/C case and the back of the electromagnet (it took about 3 minutes).

Congratulations IT IS APART! Now to put the new parts back on.

New parts: Electromagnet, Inner clutch, Outer clutch
Parts to re-install: the "Snap Ring" ("C" clip), the "KEY" taken from the old outer clutch assembly (or "off of the compressor shaft" wherever it ended up being).

Position and install the new electromagnet onto the A/C compressor "Nose". Be aware of the position of the electrical connector is to face "forward" (like the way the old one was positioned).
I used the old electromagnet to be a sacrificial part when I used a small hammer to drive the new part back onto the "nose" of the Compressor. I drove it until it was almost touching the compressor bolts. (The same position as the old one was before I drove it "Evenly OFF of the Nose" with my wedges and screwdrivers).
Position and install the inner clutch assembly onto the compressor. Apply pressure evenly so the part does not "****" sideways and become stuck. I gently tapped around and around until it bottomed out.
NOW install the Snap ring using the tool you got it off with (It should just about "Push on") until it "Snaps" (locks) back into the slot that you removed it from.
I applied an anti-seize agent on the inside and outside of the shaft of the new outer clutch before I lined it up with the compressor shaft. Remember to install the Shaft "KEY" between the shaft and the notch of the outer clutch component.
Press the new outer clutch back onto the compressor. (I used a small hammer and "Gently" tapped it to where it should be.
Install the 1/2" nut you removed from the center shaft and turn it Clockwise (Tighten) until it bottoms out.
If necessary tap the outer clutch assembly until you are sure it is back to where it should be. There should be a small gap (postcard thickness or so) between the inner clutch and outer clutch surfaces.
Using your 1/2" socket be sure the nut is TIGHT ( I have no idea what the torque specification is or how to hold the outer clutch assembly from turning so I held it with my hands until I couldn’t stop it from turning).
Plug in the electrical connection.
Re-install the plastic panels using the 9/32" nut driver on the mounting screws. Snap back in the plastic fasteners into the holes from once they came.
Re install the left front tire into the car and tighten the lug nuts to the specified torque.
Carefully remove the jack stands and lower the vehicle to the ground.
Inspect your work clean and put your tools away.
Start the car, with the AC Button (Switch) "OFF" inspect the outer A/C Compressor Clutch "not turning". Listen for problematic sounds.
Turn on the A/C, with the AC Button (Switch) "ON" inspect outer A/C Compressor Clutch is "engaged" and turning the shaft of the compressor. After a few minutes the cabin air should start to cool.
This is how it should work.
With mine, the clutch did not engage, Probably because there is no refrigerant in the system so the compressor will not engage until I install at least one can of refrigerant into the A/C System (that's when a pressure sensing switch figures out that there is refrigerant in the system and it will be "OK" to run the compressor). You cant run the compressor without it's lubrication it wont let you.
So now I'm off to the parts store for a couple of cans of Freon (or what ever its called now).
I hope this helps - Good Luck!

Do you have a 1, 2 or 4 wire plug?
