blower motor only works on high
 

I had a bad blower motor and I replaced it but its only working on high now. could it be just the switch or is there more to it than that?


Thanks

It sounds like a blower relay! Its under the dash below the glove box.

Is this just like a square box or something? what am i looking for?.


Thanks again

Its a little rectangle with 3 wires (i belive) coming off it. It's right on the side of the heater box below the dash on the pass side, can't miss it. Their are wire coils on the other side that make the resistance for the different fan speeds. I think a new one from Napa was $20

its about an inch by an inch and its silver. its got a plug that connects to it and it has 3 prongs commin off the relay. i just replaced mine on my 76 and it only cost me $10 and took 2 mins to replace. its only bein held on by one screw.

Thanks Guy's turns out that it was disconnected, hooked it up and it works just fine!.

I always wondered what that was for:-X04


Thanks again

Wow, this place never stops amazing me...I also wondered what the h%#@ that thing was....heading out to the driveway now to check it out...a fan with 3 speeds..that'll be something new.

That's what I love about this site even the small things get talked about. I would have been following all the wiring from under the dash and we all know how much fun that can be!!.



Long Live FTE!!, and thanks for all those who maintain it!
