Okay, folks, here are the 2 symptoms:

Symptom #1 described:
About 2-3 weeks ago, I'm driving on a warm day with the AC cold air blowing out the center vents.....and the air starts getting warmer....then hotish. I'm running errands, so I stop the car. Came back to the car in a few minutes, start the car, and viola, I have cold air starting to come back thru the center vents.

I'm thinking this is a possible KLIMA erractic malfunction.

It happen 3 times yesterday. AC ice cold air starts getting warmer....turn off key; restart the car, and I have ice cold air again.


Symptom #2 described:
I was playing with the AC a lot this morning. If the AC is on MAX cold (feel the click in the thermostat wheel on the ACC), the AC is icy cold and blowing thru the proper vents including the center vents. I adjust the thermostat just a bit, with the fan speed on any setting, and the center vent seems to switch.......hardly any air flow thru the center vent.....can hear the roar of air moving....buts it's not coming out of the defrost vents.....I turn the thermostat back to MAX cold, and the air flow returns to the center vent.


Weird, huh?





I replace the Mono Valve on this car (87 Champagne) back when I bought it, so, I'm thinking it's not related to it.
