A while ago I had the belly pan powder coated.  I also added the air guide under the air dam.  I didn't notice a temperature difference.

Installed.  I now need to be more careful of driveway slopes.

It has been really hot here in Pennsylvania recently that I don't enjoy driving the car.  I attempted to get the AC fixed but had a clogged condenser.   I replace the drier and condenser about a year ago but never got back to the AC shop for a vacuum and R12 charge.

Avenue Motors in Allentown vacuumed and recharged the AC, but the control signal from the AC controller is not giving the signal to turn the compressor on. They jumped the compressor to make sure the pressures were good.  I started to look into the problem by reading the service manual.  There is an AC diagnostic port.  It was a bit difficult to find and the manual does not indicate where it is adequately.  The AC diagnostic port is located on the passenger left side kick panel.

Connected the meter to read the pulses

I read seven pulses from the port, but that is "omitted" according to the manual

Of course!!!

I switched to an analog gauge to make sure it was seven pulses

Not sure how to embed that video, but it is 7 pulses.



Looking at the manual the evaporator thermistor can tell the auto a/c controller to turn the compressor off too.  I measured the resistance of that thermistor and got 3200 ohms.

Tracing back to the AC control unit

Posted Image

AC control unit.  I wonder what the H/L is for?

Posted Image

I opened the AC control unit to see if anything was wrong inside.  It looks good, but I believe the problem is in the Auto AC Control Unit.

I ohmed out the compressor on switch from the connector to the relay in the engine bay and it is good.  So checking everything else I believe the unit is the problem.  Now onto the Items Wanted section.

The H/L is basically a temp setting. I cranked mine from factory, all the way to max towards the L and got several degrees cooler discharge temp from the vents. I believe I have another tested good unit I’d sell

Sounds good. PM me. I have a local source that is searching for one, but I think I'm going to buy a couple of them to be sure.
