Hi,

A probable temporary remedy is to add more silica oil on the fan clutch. Silica oils has a distinctive property, it exhibits the exact opposite reaction of regular oil. Regular oil when the surrounding temperature goes up tends to be viscous, thinner. The silica oil tends to be thicker and hence the fan clutch would engage earlier/harder. Depending on the design, there would be a not easily removable plastic or rubber grommet/stopper somewhere in the body of the clutch, this is where you could add drops of the silica oil.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

A/c works on and off at random


does your car have enough antifreeze in it? If the car is running hot then your a/c is not going to cool properly. I would check that. I would also check to see if the clutch on the air compressor is trying to go out. To check the clutch grab the front pulley of the compressor and if it is loose or wiggles then your clutch is going out. You can replace just the clutch without having to change the entire system.

Air conditioning blows hot and cold air


You will need to know if the compressor is working when it blows hot air to proceed. It could be an electrical problem, a blend door problem, or the a/c clutch on the compressor.

My AC blows hot air at stop lights. It works great when the car is running on the free way, but does not work when the car slows down. Any idea what the problem is????


Have you radiator clutch fan check out, sounds like its bad, air blows through radiator and a/c condenser while driving and no air blows through at stops, will cause a/c pressure to go up and not cool.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

A/C blows hot air going uphill or pulling a trailer.


you will need to change the clutch fan, under load or high speed will heat up the engine and the clutch fan should ingage to pull more are through the radiator. Also at idle with no air moving through that radiator the clutch should ingage to pull air through.

Air conditioner blows hot air


this can be a few different things going on. 1. does the clutch on your compressor engage when a/c is turned on? If so, does it cycle on and off constantely? If its cycling, your low on refridgerant, which indicates that theres a leak. System needs to be checked by professional. If compressor stays on, and you got hot air, it indicates that the problem is with the heater control valve. Normally, this can be found connected to one of the heater hoses located on passengerside engine compartment. It might be electronic, or vacuum operated.
