HI!!
Your problem could be the fuse, the circuit uses a 30A fuse, if you use any lesser amperage fuse, it will blow out. If the fuse is OK, then your problem is the Blower Motor Resistor $27, it is located in the blower motor housing and it is the part where the blower motor and the electrical plug connect. To remove it, unplug the two connectors and remove the two fastening screws. Here is a picture of the actual Resistor for easier identification.

A/C and Heater Problem


Well,you eliminated the resistor,so it probably means the blower motor has shorted out.Either that or something has gotten into the blower wheel and jammed it. If you can bypass the resistor and just put 12 volts into the motor,do it.But don't hold it long,as a direct short can cause a fire without a fuse to blow for safety.
In other words,prepare to buy a new heater blower motor. don-ohio

1992 gmc pickup keeps blowing heater fuses I replaced the blow motor and it keeps blowing


Have you replaced the blower resistor . some times they can cause the fuse to blow . You may need a muiltmeter to test the current draw on the blower motor circuit. the draw should be less then half of the rated fuse .( 20 amp fues draw is less then 10 amps) You did not say but does the blower work on high only or the lower speeds with out blowing the fuse ? if it does work on low or high with out blowing the fuse i would replace the blower resistor

Non-blowing heat and A/C blower fan.


Did u test the THERMAL LIMITER on the blower resistor? this is the part that burns out, the resistors always look fine. Replace the resistor, it is cheap and i am sure it will fix the problem. U may also wish to check the 30 Amp blower motor relay circuit breaker in the underhood fuse box, I believe it is marked HEATER.

20 amp fuse in the box under hood that keeps blowing


Does it only do this when the heat or A/c is on full blast.. ( I had a few of my customers with this problem and they needed a new blower motor..)

Heater works but fan doesnt work


on the inside of the fuse box door there is a list of what each fuse is for, fuses will be numbered with coresponding numbers and explanation of what there for. also if fuse is ok, chanses are its the resister, its located behind glove box on top of heater box 2 screws hold it in heater box, electric plug with 4 or 5 wires going to it. i just went thru this with my 1995 chevy 1500 pick up. but before you go thru that chk. fuse, chk motor, run 12 volts direct to motor see if it works. now did the motor just quit? or did it work on a couple of speeds before it quit? well at any rate if the motor runs when 12 volts are put to it odds are its the heater resister.

Blower moter will not work


Check the 30 amp fuse in the fuse box under the instrument panel on the drivers-side. If it's alright remove the connector from the heater resistor mounted on the passengers side close to the blower motor. These are usually secured with small hex headed screws.With the ignition switch in run, turn the heater on and use a test light to see if you have voltage coming to any of the connector pins. If you don't you'll need to trace back until you locate the problem. If you do have voltage check the resistor. Don't forget to turn off the ignition switch.
