1. If I'm looking to replace these resistors, what do a look for? Would they be called "fan speed switch resistors", for instance?
2. Would I find them at an auto parts store like Pep Boys, or would I need to go to a dealer?
3. Once the blower motor is removed, is it "obvious" where the resistors are located, or does it take some fair knowledge to figure that out?
Cheers,
Doug
another method that works with my size 13 fingers, If you can find the cable with your fingers while sitting in the drivers seat, You can force the knob while using your fingers to keep the cable from kinking.
I am no mechanic just telling what happened to me . Good luck
The problem is that we can't get the compressor clutch to engage. The relay seems to be working and we hear it when we turn the a/c on from inside the car. We tested the old compressor after we took it out by running wires directly from the battery to the compressor and it engaged. That made us think that maybe the a/c wasn't working NOT because the compressor was bad, BUT because it wasn't getting enough juice to engage the clutch.
Does anyone know how many volts the a/c compressor needs (at the compressor terminals) to engage the clutch?

Thanks!
If you're charged, then I'd suggest you find the pressure switch and test it by bypassing it. If the compressor engages when you buy pass it, then that's your problem--the switch (or low refrigerant if you haven't tested refrigerant pressure).
You can also test everything electrical right at the compressor's electrical plug-in by by-passing the pressure switch and reading voltage at the compressor.
Try not to run the compressor if you have little or no refrigerant.
If you are fully charged, and if you've bypassed the pressure switch, and you still get no clutch engagement, then you must have a bad HVAC control module in the dash.
thank you for your help

Thanks. :confuse:
I'm trying to resist taking it to a shop and spend hundreds to find it was a switch that is screwed on with two wires to unhook and hook back up or if it was a blown fuse.
Thanks.
My '03 Cavalier is doing the exact same thing. Were you ever able to figure out what was wrong with the A/C? We filled it up with freon and it didn't help the issue.
Thanks!

I don't know what else to do, but get these things fixed. I'm on a fixed income and can't afford to buy a new car. This is the second time that I've needed a new motor for my driver's side electric window. I didn't see anyone else in the forum with this problem. At first, one of the mechanics told me to get the dye to check for leaks in my A/C. Later the other mechanic told me I needed a new compressor. I hope that I am making the right decision to have these items repaired. Any thoughts?
Then after they fixed that, I began hearing a clicking noise in the same area. They claim it was the fresh air door that was not closing properly because the motor went bad. What lovely timing. They unpluged the motor so I won't be able to turn the dial to get outside air, I can only get recirculated air. Big deal...I can live with that small problem, so that won't be getting fixed.
Good luck on yours.
If I have the air turned on (as long as I am moving) cold air will seep through the vents, but the fan will not blow. So the compressor is doing its job in cooling. I bought a new blower motor and tried to replace it, but it seems that there is no power getting to it. The power switch works since it does kick on the compressor and the light comes on to indicate the air is turned on. So it's not the switch. I've tried replacing some fuses but it still doesn't work. I've tested the pigtail that runs right into the blower motor as well as another one from the same area and neither are getting power.
Single mom with these three children. I only know enough to be dangerous when it comes to cars. If you tell me what to do, I can do it. But I have no idea what to even look for at this point. I've tried doing searches online and keep coming up with nothing.
Thanks for any help you can give.
