When you say fan I assume that you are talking about the heater fan?? The fuse and relay are usually plug in modules. Fuses are usually under the dash and relays and some fuses are under the hood in a large black box on top of the drivers side fender. A description of fuses and relays is on the inside of the lid that you take off. If replacing them doesn't work then time for a new fan.

1995 GMC Sierra fan blower not working.


In the beginning you should check for voltage and ground.
The 50amp fuse marked AC powers the blower motor and the motor is grounded.
The high speed relay bypasses the resistor. So you should have power coming from the fuse and thru the high relay. Then the resistor for the other speeds gets power from the heat and ac control module which also controls the blend doors.
You may need a shop manual or repair book to get the diagrams.

2005 gmc sierra heater fan quit working. I lost the fifth speed months ago and a couple of days ago lost the other four, the first day the fan would come on sometimes while driving then quit after a while...


1-4 speed are the blower motor resister . It controls all 1-4 speeds, also it's under the passanger side dash around fan, the 5th speed runs off a fuse the is located in the fuse box. It's one of those square fuses , not the relays but fuses. The resister will run $15 and fuse $5 . Good luck. I have replace these before
