No a/c when Idling, Engine heats up. Fans come on for a few seconds, but not very fast, then quits. A/C works when your driving fast enough to get airflow across the condensor.
Leaking coolant and overheated, my car stalled during rush hr. It is not drivable because it would overheat and the engine would shut down. Steam was coming out of my hood. Fan was not working.
Car overheats when idle and ac won't blow cool. Car rides fine and air blows well when in motion. Only issue is when it is idle for several mins.
car overheated, steam was coming out of the coolant bay, and was spewing out coolant. recall on SSP71 Fan Control Module; replaced and installed AJ51-15-15YA for free. problem solved. basically, this error makes A/C, radiator fan, and other stuff malfunction.
driving down the road and i felt a little jerk then the temp gauge went all the way to cool and the at light as well as the traction control light came on
Fan continued to run for some time after engine shuts off. Fan comes on and winds up as soon as engine is started.
During summer Air would not cool car. Dealer said the module had already been replaced twice and they would not replace it again. If they replaced it it was without my knowledge.
ENGINE OVERHEATING WHEN IDLE, FAN WON'T START, NO AC WHEN IDLE
Fan keeps running for seconds up to minutes after the car is shut off. Had fan module replaced, $350 later, still experiencing the same problems.
Fan continues to run after the ignition is turned off, repair shop said cooling system was okay, but for $85 they could connect it to the "computer" to tell me the same thing I just found out on the Internet, I will be calling Mazda to see what they have to say.
mazda replaced the fan module, took 6 hours for this to be done.
Car runs hot cooling fans are not coming on at all..car use to stay cool as long as im driving at speed and never reached the "H", now it doesnt cool even when I am driving! Recently got coolant sensor replaced (seems like the car wouldn't cool since the replacement)...whats wrong with my car?
My Mazda 6 v6 2010 Model has this exact same problem. The dealership says they have to replace the entire fan assembly at a cost of $1,275 and that this is not covered under the 100,000 mile extended warranty on my certified pre-owned car.
AC stops working when at stop light. Engine temp rises. When driving at speed AC will start working again and engine temp returns to normal.
Im having a problem where my engine fan stays for a few seconds or sometimes even minute. I did a search on Google to find out if this was a common problem and it looked like it was. I found a video of a guy explaining why this problem is happening and it looks like it is due to a failing Fan Control Module. I bought the replacement part from Rock Auto and on the instruction sheet it stated that before this part is installed, that you need to first find out if you have a failing fan motor. As I look through the comments here I notice that some of you have already went through 2 or 3 of these Fan Control Modules, and the reason for that is because if you have a malfunctioning Fan Motor that, would be the reason why the Fan Control Module is bad. A malfunction Fan Motor will blow a Fan Control Module every time. Make sure your Fan Motor is in good condition before you install the Fan Control Module or you will keep burning it.
Fans work sometimes. I replaced the module but did not correct the problem. Now 3 months later back to the same overheating problem but, now the fans do not run.
It overheats when sitting still , no sign of water leak , and no water in oil ... I haven't got it fixed yet looking for answers ..
Well it started over heating, and the coolant resevior was always full, no leaks, but the fans won't turn on, so, told it would have been the relay switch from the thermostat to tell the fans the engine is too hot(don't want to blow the head gasket right?) but the dealership says. 1695 to fix . Autozone says some of the parts are 75-200$ , what do i do when it's at the dealer for weeks now and they can't do a thing about it
When I turn the car off. The cooling fan stays on and drains my battery. I have to unhook the connection in the engine compartment, and plug it back in when I need to use my car.
heating up. replaced RADIATOR at recommendation of 2 different mechanic shops. WAS NOT the problem. Hose connection was
seen to be the problem. Wondering if "FAN" was operating correctly. This may explain it.
When air conditioner is turned on needle starts moving to H
