Hello,
I bought a 95 truck last year. It runs great. But the heater has never worked unless on high. Then it started to run intermittantly. Now it has stopped all together.
I replaced the blower motor. Still doesn't work. I was told it might be the resistor or the switch. Only problem is I don't know where they are and the worthless chiltons manual doesn't even mention one!
Do you have any idea where the resistor might lie and what it looks like?
Also when they mention the switch is that what is behind the knob I use to turn it on?
I believe the heater has 4 speeds when it works. Any help would be appreciated.
Cheers

Check and test the blower motor relay located on top of front AC/Heater blower housing, also the blower motor resistor is located on front of blower motor housing-sorry no pic available

Hello and thanks for the donation!

Yes, your vehicle's heater switch is the knob that controls the level of speed. Your vehicle's blower motor resistor is located on the blower motor housing itself, under dash.

I'll take a picture of the blower motor tomorrow but I still don't understand. I bought a blower motor. Has a thing that looks like hamster wheel. Is the resistor in side somewhere. The back doesn't seem to have any part you would remove. There is just a prong sticking out to hook to hot wire. The wire is purplish color and runs off into the interior of the dash somewhere?
If the resistor is a part of the blower motor then that isn't the problem. As it is brand new (or I guess it could be a faulty one).

Ok so most likely it isn't the resistor if that is part of the blower motor itself. Since I did replace the blower motor yesterday.
I'll see what it takes to get to the back of the heater knob. I am guessing at least part of the dash has to come off?
The local parts dealer said they have a switch. Thanks for the info.

Ok I have changed the switch, and the relay and the blower motor. I am getting juice to the motor when the switch is turned to high but the motor doesn't turn.
I get no power on any of the other settings.
Does that mean it is the resistor?
I think that is all thats left to change!
Cheers

Do this disconnect the purple and black wire connector on the blower motor-power the motor from the battery positive connect it to the purple wire the black wire is the ground circuit

If it powers up its coming from the AC/Heater control module. Also check the heaterand AC fuse 25amp in the fuse block this one powers the module
