Im trying to locate the fuse for the rear blower in my 2008 gmc arcadia, can anyone help me


RR/HVAC fuse 30amp located in the under hood fuse box. You can check it but highly doubt it's the problem . More then like it's the blower motor control module that's bad .
Circuit/System Description
The auxiliary blower motor is a variable speed fan. The HVAC control module controls the fan speed by sending a pulse width modulated signal to the auxiliary blower motor control module. The auxiliary blower motor control module varies the duty cycle across the auxiliary blower motor in relation to the pulse width modulated signal. The auxiliary blower motor speed can be adjusted from 10 percent to 90 percent duty cycle (PWM), 90 percent is high speed fan.
Watch this video for testing purpose's only , this is a front blower motor control module . Same way your back one works . GM is GM Chevy , Buick ,GMC , Cadillac .

My fan stopped


If you are referring to the cooling fan, first check 5A FUSE 16 and 30A FUSE 41 in the front power distribution box. If the fuses are OK, the temperature switch, the pressure switch, the speed relay(s) or the auxiliary fan motor(s) could be at fault.

2003 Jeep Grand Cheeroke radiator fan runs when car is off draining battery. Could it be the relay? If yes is the relay in the fuse/relay box under the hood or under the passenger headlight?


After checking the conventional relays and fuses, we found an additional auxiliary cooling fan relay behind the front bumper. Once replaced, all is well.

The fan relay is likely shorted and keeping the fan motor energized; to check this you can remove the relays from the fuse panel... remove the cooling fan rely from the underhood PDC (Power Distribution Center). Fot this and additional fuse details, check this link: wjjeeps.com/fuses.htm

Hope helps.

How do I remove condenser fan from a 2004 jeep grand cherokee limited


If you are talking about the cooling fan between the radiator and the engine [with the 4.0L engine] then this fan comes out through the top along with/attached to the radiator. If it is a 4.7L hydraulic fan then it can be removed without pulling the radiator. If you have an auxiliary fan ahead of the radiator then you may have to pull the grill and related parts surrounding it to get it out. None are real easy to get out and require a fair amount of patience to remove. If you have an electric fan check to be sure that you don't have a blown fuse that is preventing it from working. Usually it's a fairly large fuse of 30 or more amps. These fans can become frozen in place in winter and will cause the fuse to blow when they try to turn but the problem may not be noticed until the weather warms up and they are needed for a/c operation.

1995 honda accord ex auxiliary cooling fan not engaging


The accy fan you are refurring to is actually the a/c consensor fan.The only time that fan operates is with the cycling of the a/c system.Verify by turning a/c on ,fan should come on & off with a/c cycles..

Ac is not working i think is a relay because the ac cluch wont star


If you have cooling fans, then it could be your compressor itself. If you hit the A/C button, and there's no cooling fans, try a new "Cooling Fan Control Module" it's a common problem on early 2000 VW's.

I have a 93 jetta with the 2.0l engine. Engine heats up when at idle with the a/c on. Auxiliary cooling fan is not working at all. Where is a good place to buy the auxiliary fan? Or is there anything else...


Check the fuse to the radiator fan and the relay's. Also check the wire harness and connections to the electric fan. Most of the time it's going to be a bad relay or corroded wire harness which is cheaper then the fan unit it self. Recap: check the fuses and relay and also check the wire harness at the fan to make sure there is 12 Volts to the power wire to the fans. Easy way to do this runt he engine and turn the A/C on hi and check radiator fan wire harness for 12 volts. If there is no power then work your way back to the relay, change the relay if the fuse is good. Good luck and keep me posted, be glad to help
