#58 of 86 disconnect battery, now have a/c issues....
Jul 13, 2009 (6:58 pm)
Ok, i replaced my tps in my 2002 Chevy Cavalier. Everything was working perfect.. So i thought I would disconnect the battery to reset the codes and then I had problems. My inst panel quit working, So i took out the cluster fuse and got all the gauges to work, but now my a/c turns on but i cant change the speed nor can i change like from floor to defrost. It blows cold and it blows a lil out of my floor vents and out of the dash vents and a tad bit out of my defrost. I can change from cold to hot and

I realize this is an older post; but seems to be a re-occurring problem. The cable that connects on the backside of the climate control knob is known for kinking. If the cable is not frayed yet, you can pull it off the back of the knob and straighten it (this does require, laying on your backside on the passenger side floor, and a flashlight helps if you are trying to accomplish this for the first time....if the cable is frayed you can replace the cable. It is the same cable as the "heater control cable"; to replace it, it is a job that can be done without removing the entire dash, you will need to remove the plate over the brake; and again, plan on a lot of time on your back with a flashlight. I just replaced mine over the weekend, and was able to straighten a co-workers today.

I also have discovered the air control knob kinking. I fixed it using a need nose pliers but it just wants to kink again because the control box wheel or control box "guts" must jamb at times. I have checked for clearance and there is no rubbing on the wheel by the cable. Question - what is the specific cause for the failure? Has a air gasket come loose inside the air control housing that interfers with smooth operation? Also, with all my "experimenting", I found that if you allow hot air to heat up the air control box, the control knob will then move freely to all positions.
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.

#62 of 86 noise from heater

A loud clicking sound started on the passenger side of my 2004 Cavalier. I traced it to the blower motor in the car. The noise is there even when the fan is off, the noise stops when I move the climate control switch to outside air. Thanks Hams1
#63 of 86 brakes noise

when I press on the brake pedal a noise is coming from the read brakes, as if it was a bearing noise. The noise is only there when I apply the brake pedal hard enough to stop the car. Thanks Hams1

had same problem . Turned out it was the serpentine chain that should have been replaced as manual said. One garage told me the S belt is fine, went to another place and told them i wanted it replaced and problem was fixed. To be fare to first mechanic the belt LOOKED fine on car but once off you could see it had to go.
I am no mechanic just telling what happened to me . Good luck

#66 of 86 How many volts does it take to engage the a/c compressor clutch?
Apr 17, 2010 (5:54 pm)
My father and I just replaced the a/c compressor and condenser on my 2000 Cavalier. The a/c hasn't worked for years and I finally decided to fix it myself as opposed to pay serious $$$ to have someone else do it.
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?

Now you know it won't engage unless you have the proper amount of refrigerant in there, all charged up, right?
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.
