On my 2001 Honda Accord EX, the cooling fans will not come on when the air conditioner is turned on and it will not cool. What is causing this?


sounds like an air conditioning issue if your only complaint is the fans not coming on when air conditioning is used. you need to have the a/c sys checked out to see if you have a leak or perhaps refrigerant may be low. sometimes you may have a compressor that no longer works so the system may not be building up pressure so the pressure switch does not cycle the fans.

The fan wont work car does not get hot shut off


cooling fan works on a temp sensor in the engine block. it only turns on when the temp reaches a set limit and shuts off when it gets below a set limit.. cooling fan components are , fans, fan relay , and temp sensor . best way to test the fans would be to let the car set running and watch the temp till it goes up to 185 -195 deg. at this time the fans should turn on and the thermostat should open and cool the engine back down. also when ever the air conditioning is on so should the cooling fans be on. if the fans do not run the check all components till you find the broken one. fan relay and air conditioning relay are separate but work the same. and will interchange

Air conditioning wont cool went the car is park


Sounds like your condensor cooling fan isn't working. It cools while driving because air is forced over condensor while driving. Tio prove this, place a box fan in front of the car and turn it to high. Watch it start cooling.

I have a 2006 jeep liberty with a 3.7. in normal driving conditions is does not overheat. if i am 4x4ing or with the air conditioning on it will overheat. The electric fans works and the fluid level is...


Do you know for sure if the radiator fan comes on? It should be coming on for the a/c, and it should come on BEFORE the engine temp gauge begins to climb.

Also, do you have obstructions in front of the grill? I would think that you said no blockage to the air intake, but also I could think if you have a winch. Is there any chance you have mud/debris in the radiator fins?

Bugs would be in the a/c condenser. Have you looked at the engine radiator behind the condenser? It's kind of hard to see. You may have to remove the plastic cover.

Make sure the fan goes from low to high speed; when the jeep starts to get warmer the fan should go from the normal low speed up to high (you usually will know it because it really is humming out there on high). It may just be hot enough that low speed can't handle the heat load of the air-cond and the engine in traffic.

The air cond gets the air before the radiator so if the fan is coming on low it will keep the condenser cool enough to have decent A/C performance... the dealer should also be able to test low / hi radiator fan operation.

Tell us news, hope helps.

I'm having problems with my audi that started today. It kind of bucks while im waiting at the stop light or have it in reverse. I tried turning off the air condition and kept it in reverse for a little...


Most cooling fans will turn on when the car is cranked. The bucking could be from when the engine compensates for the added load thats when you feel the buck. If you think the bucking is excessive the engine maybe compensating too much and you may need to run it by your local shop. Call your dealer, it might be a known issue or recall.

Overheating


I am not an expert on Mazda vehicles but sounds like your fan temperature sensor is not working properly. My fan comes on low speed when the temp hits 205 and goes to high speed at 220 or when the air conditioning is on. You had better get it checked by your dealer or service tech.

Fan blowing while car is off


If the A/C knob is not set to 0 at the time ignition was off, the fan could run for a little and then off itself.

Temperature goes up when air conditioning is turned on


your car has two electric cooling fans one is specifically for the added heat load the A/c puts on the system. . This fan isn't turning on...check your fuses and the fan relays
