Recentley I have been having issues with my ac/heater. Sometimes it works but sometimes it doesn't and the problem is that it doesn't blow any air out at any speed. I was quoted 600 bucks to replace resistor and motor but do both need replacing? Seems like an easy fix I just don't know what to replace! Any help would be great and needless to say 600 is a little much

isn't the resistor like a $20 part that just goes under the dash?

I wasent able to find it for some reason from ford parts online but the quote from good year had it at something like 150

Search this site for a picture of the resistor. If my memory serves correctly (I'm an old man), the resister is behind the glove box area; simply press the sides of the glove box, and it will swing completely down, giving you access to the area where this resister is. $150.00 is way too much for this resistor!

Do you have a simple test probe/light or a multimeter? You can turn the key to on, and operate the fan switch, then probe the connector to the fan/blower to check for voltage; this would help in identifying if the blower is bad (power to the plug harness, but no blower operation), or if the fault is at the switch.

Usually the resistor causes no high speed fan; the lower speeds will work, but no high speed if the resistor is faulty.

Depends on price if u have climate controll or not both r easy fix yes on floor under glove box usually

Bucko, I think its the other way around. Every resistor failure I've experienced would have a high fan ( no resistance, full voltage) but would be missing one or more lower speeds.

That's been my experience as well, usually low and medium speeds stop working.

Yep, you're right. See? I am an old man, with good memory, just short.

Now where did I park my truck?

I get no air coming out which means most likely the motor correct? I'm gonna test it when I get a chance for the voltage

What year truck do you have and do you have maunal or auto a/c?
