Back in December 2007, I was involved in a fender bender with my '95 Maxima which caused considerable damage to the front body. My front fender was uniformly pushed inwards a few inches. Under the hood caused a few migraines, as the front reinforcement bar [I'm asumming it to be part of the front chassis] was pushed inward, slightly bending the radiator, thereby causing the front hood latch mechanism to be bent [which causes the hood to close, but not lock]. Everything worked fine for about 4 months; performance was unaffected, cooling was also unaffected. However, around late April, I noticed that the AC had stopped working, and I have yet to replenish the R-134A refrigerant as needed. I have also noticed that my engine heats up much quicker than before; when before short trips less than a couple miles my engine temperature was below the middle of the gauge, short trips now make my engine temperature rise to the middle of the gauge. An added note would be that i noticed my cooling fans no longer engage. I'm asking if the failure of the engine cooling fans has any direct impact to engine cooling, and if so could that also factor a problem with the A/C?

Re: Cooling Fan, Cooling Sytem, AC; all connected?
Yes, your cooling fans need to run to cool the engine and to run the A/C. Those 2 fans are beeing used to cool of the engine and the A/C condensor at the same time. The fans actually slow down and speed up depending on how hot the car is running and on A/C beeing turned on and so on. If your fans are not rinnung, check the fuses and fusable links. They are marked on the cover of the fuse box. It sais "cooling fans" chek that. That's inside the car. Under the hood there is abother fuse box with fusable links. Check those also. There is a relay too, but check the fuses first. The relays are pretty booletproof. Do a quick check. Turn the A/C on and see if the fans are running. Let me know what you find.

one fan is for cooling the other is for ac when the ac compressor is on,if it doesn't run at all at any time possible causes could be,fuse,fan motor,control circuit.Cooling fan usually comes on when engine temp reaches around 210-215 ish
Where is the leak on the radiator? (front, side, top, bottom...)
My guess is that it might have also caused a leak in the condenser, or the lines going to the condenser. The lines are connected on the right side of the condenser, which is mounted right in front of the radiator.

Possible causes- Fan control relay harness is open or shorted - Fan control relay circuit poor electrical connection - Fan cooling fan harness is open or shorted - Fan cooling fan circuit poor electrical connection - Faulty fan control relay - Faulty cooling fan 1 - Faulty ECM (very unlikely)
The simple answer to your question is that the engine cooling system is malfunctioning. The sytem must be properly diagnosed to determine the actual cause. It could be anything from a thermostat that is stuck closed or a cooling fan circuit malfunction, or even a water pump that is coming apart internally.
Is your radiator cooling fan operating when the A/C is turned on? The cooling fan should be running at all times with the A/C on. If it does not, then your problem is being caused by a bad cooling fan motor, a bad cooling fan relay, a broken fan motor circuit, or broken fan control circuit.
It is very common for all of these lights to come on all at the same time. They are all related to your Antilock Brake and Traction control system. ABS = Antilock Brake System, TRAC OFF = the traction control system is disabled - either because there is a malfunction in the ABS system or you have turned off the traction control button. VSC = Vehicle Skid Control. - (which uses the ABS and the Traction Control to function.)
The most common cause of these lights coming on is one or more defective wheel speed sensors. Although there are many other possible causes as well. Your ABS and Traction Control system must be scanned for fault codes to diagnose the problem. If you had damage to your wheels/axles during your "fender bender" this may have something to do with it. Otherwise it may just be coincidence that part of these systems failed right after your accident.
There are two relays for the cooling fans, one or both may be bad.
With the engine running and the AC on, the fan should be running.
With the engine hot the fan should cycle. I believe the relays are mounted on the drivers side front fender on that model.
I am having the same problem on my 98 with 160k. I have determined that the right fan is the ac fan. With the engine hot and the ac on, I can tap a blade with a small stick to make the fan start spinning on its own. I thought this was a relay, but this should not be a relay if the thing will spin-up like this. Also, the main cooling fan is not, in my experience, always running when it should. I now suspect the same problem. Therefore, I am thinking I will need to replace both fan motors. I hope this helps. This has been driving me crazy for about 9 months.
In the front of the cherokee, right side under the bumper there is a football shaped plastic canister.
The canister is a resoiver for vacuum that control the heat and defrost
doors. Either it is cracked from the fender bender or the body shop
didn't connect the vacuum lines.
