I don't know what testing you have done? Any applicable hvac trouble codes? Note the diagram, is the compressor clutch energized? In the diagram, top wire for compressor clutch is voltage. The bottom wire is ground. Check voltage and ground with everything turned on, use a test lite. There are fuses involved, also. Could be problem with pressure switch?

SOURCE: 2001 chevy malibu- when car starts cooling fans do not come on but then do

your coolant temp sensor on the engine block is probably faulty, however, keep in mind that if it really isn't all that hot outside they may not need to turn on. Once you activate the A/C the fans come on automatically since they have to cool the condensor...

If your car is not overheating do not worry about it.

SOURCE: the cooling fan doesnt work on my 91 honda accord

  1. Cooling fan Relay
  2. Engine temp Sensor
  3. Cooling fan itself
  4. If While A/C is on Fan does not come on I would Check Fan By unplugging it first than apply Pos+ and Neg- to it if it comes on that's eliminated Then go to step 1-3 one of them is bad I usually replace Engine temp sensors no mater what they are Crucial components for the safety of the Engine.

SOURCE: 98 Saturn SL AC/cooling fan will NOT work

Do not let this car over heat a blown head gasket will ensue. Locate and replace the fan relay, if that doesn't fix the problem unplug fan and use jumper wires to ground the plug then feed power to the positive side of plug to check fan, if that doesn't work replace the coolant temperature sensor located somewhere near the intake manifold or thermostat housing area.

SOURCE: 1998 dodge caravan. AC problem. My AC doesnt work,

do this calibration reset, it will usually rest he lights and the ac will work again, if it doesn't reset you have a part failure and the dealer you need to hook a Chrysler scan tool to diagnose the problem.

CALIBRATION/DIAGNOSTICS TEST ENTRY
TO INITIATE TESTS:
Set Blower motor ON HIGH
Set Mode position to Panel
Set Temperature to Cold (Both slide pots if equipped)
Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light)
RESULTS:
All LED's will turn on for 5 Seconds
Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cooldown test is running if A/C and RECIRC are alternately flashing.
Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit.
After all tests have passed, Calibration Diagnostics and Cooldown can be run separately

Bleeding cooling system on 2011 Chevy aveo . Ware r bleeder screews?


If you have air in the cooling system follow this procedure.Remove the filler cap and place a large funnel over the opening.A cut out large plastic container would do.Turn on the heater not the fan and run the engine to operating temperature.Burp the system by squeezing the upper rad hose(It's hot).When you don't see any bubbles you're done

My 2010 Chevrolet Aveo LT is making a clicking sound when I turn on my AC, but I turn it off it stops- occassionally blowing cool air but then turning hot. Any suggestion for an easy fix without breaking...


Your system is low on R134....the clicking is the compressor engaging and disengaging. You will get cool air while compressor is on, then warm when its off. They will act this way when R134 is low. Now either a leak in the system, or the system just needs a boost. Another thing to check is the condensor fan under the hood.When you turn the AC on,the condensor fan needs to be running, if its not then its a bad fan motor,relay, or fan sensor. I don;t know what your abilities are, but maybe armed with this info you can work on it yourself, or at least not get taken advantage of at the mechanics. Good luck !!

2009 chevy AVEO 5 ac blows hot air


The guage needs to read between 35/40 psi.. If its much higher you may be overfull, this causes it to not cool.. Fix by letting some freon out, then top it back to needed pressure.. If pressure is correct, it would be a clog in the system.. Usually an orafice tube or accumulator..good luck!

2007 chrysler pt cruiser cooling fan does not work with ac


If refrigerant is low , high side pressure may not be high enough to engage the pressure switch to kick on the fans. Have the a/c system evac'd and recharged to capacity then recheck fan operation. Also, extreme cold weather can reduce high side pressure on a fully charged system preventing fans from coming on.

2004 chevy aveo when i turn ac on it runs hot and when i turn ac off it cools down


The AC puts allot of heat load on the engine so of course it will run hotter but not overheat the engine, if that happens you may have a clogged radiator.

Check for power to the fan and for a good ground. If those are both present then you would need a fan. If your old fan rubbed a hole in your radiator then I would definately check to see if the fan has play in it that would case it to hit the radiator.

Unable to get my 2003 chevy blazer to start. has been acting funny. the hot air has been running cold and takes the ac a long time to get cool. the engine runs hot.


get a mechanic to have a look ,water level low hence the heater is cold and ac taking a long time to cool because the fan isnt starting up when ac is turned on ,Sounds like your fan is playing up and you may have cooked the head gasket??
