look under your back seat

you did not apply vasoline to a nylon washer to keep it in place during assembly. the washers is out of place and will cause this problem
in the old rear wheel drive gm cars if this was done at least you had 1st gear only.

check your dimmer-you may have accidentally turn the switch on-if not the dimmer switch will need replaced

could be head gaket faliure have it block tested

Get a battery check first and have it charged. Then, switch off all lights, radio, ignition switch. Reconnect the charged battery negative ground first, then, the positive terminal. Find if there's a spark. if it does, then, you must check your electrical wiring since this is grounded. Do not connect the positive terminal. Clear the grounded connection first. If no spark, go ahead. Crank your engine, and let it run at neutral position. And check the voltage that goes out of the alternator, this must be more than 15 volts DC. Then check the voltage output of the regulator which must be 13
to 14 volts DC. However, if you cannot get the right voltage at the
alternator., you have to replace it. Then, you can check the regu-
lator output voltage, and get the right voltage. Get this done,. and
send your e-mail for the result.

Works great in all cars, do a compression test before and after and you'll see results.

Rev the car to around 2500 rpms and run it through a vacuum line while the car is running (brake booster line works good) if the car doesnt stall turn it off immediatly and let the car sit for 5 minutes. Restart it and enjoy the smoke show, rev the motor a few times and take it for a drive. I do this in all my cars (Volvo s70, Isuzu Trooper, and Ford Taurus) and do this treatment every oil change.

the switcwes that turn on lights when door is opened are located in the door latch itself.spraying latches in door liberally with CRC may work consult a repair manual for exact dash bulbs & procedures.

Remove the regulator cover and inspect the relay contacts (remove the negative battery terminal) and interior of the case for rust or corrosion. If the contacts have a rough pitted appearance, you can lightly file them (with a very thin small file) (don't use sandpaper or emery cloth). Check the resistors under the base for tight connections. Also, check the brushes in the generator for length and spring tension. Tighten the armature and field connections--they shouldn't wiggle in the generator body. Check the fan belt for condition and proper tension. Make sure the generator turns freely with the belt off--no noise or side to side movement. Check the body-to-frame grounding strap for condition and end-bolt connections. Good luck!

sounds like a bad or lose body ground

power steering pump is/may be going bad or the rack and Pinion unit could be bad.

By not responding are you saying when you turn them on your getting no air?.If that's the case your blower motor is bad. Hope this helps.

check the freon level, common proplem

very well could just be a bad tire. I have replaced brand new tires straight from manufacturer you should check for a bad wheel or balance of tire and perferabley somewhere where they do a phase match balance.

the interior handle yes.
usually the outside trim and then the handle stays in place,and the panel goes over it.
the GM service manual will save you alot of grief.there is an exploded view .

Most likely spark plugs and wires. Coils usually kill two cylinders at the same time. Use only ac delco parts. trust me, it is something you don't want again soon.

It sounds like you have a key tumbler issue. Try spraying some WD-40 into the cylinder then blow it out with canned air, it should free up the tumblers for you.
Good luck, let me know.
Regards.

should have pic of pattern on hood or rad support if not all groved wheels inside of belt and all smooth wheels outside belt usually when almost done u should only use tensionor to finish putting on belt at the alternator worst comes to worst go to used car dealer n fake looking at car like yours and get pattern

I had a very similar problem with the same car, it turned out to be a bad battery connection. Very simple solution, I guess I was lucky. I hope this helps and sorry for the late post. If you would consider selling it please write me at reitee at hotmail.com
Good luck.

Sometimes you can flip the switch up and down very rapidly and it will clean the contacts. May have gotten wet at some time. Ive used this trick several times, especially GM products. Use your thumb and move it very quickly and with a little force.
