89 climate control problem

[donman60]

I have a problem with my climate control.
Everything works good a/c and heat.
but after a while the display goes crazy.
All the Led lights start flashing and the the temp display either goes out or displays all different kinds of bars.
If I touch the off button the display goes back to normal for a while
During this time the setting which I have originaly set remains unchanged.

Please help

Do you have the all-electronic temp control?
I have it on my 89 and there are no red-colored lights or bars.
There's just the green-colored fan speed (2 digits) and temp (2 digits), and the yellow lights indicating mode - off auto econ vent heat defrost.
Does this reflect your display ?

Yes, mine does the same thing... I've read somewhere that the contacts need to be cleaned. Who ever said that using a pencil eraser works just fine; unfortunately I've not had the time to test that out just yet.

Good luck!

Had the same problem with my 88. I did take the unit out and cleaned the contacts several times. Since the fix only lasted a short time I ended up buying a new unit from one of the big parts places (MAD, Ecklers, etc.). Can't remember which one. That finally fixed the problem. Give the contact cleaning a try though. It's definitely cheaper and may work for you.

This has happend to me a couple of times as well but not all the time. So far it saeems to clear itself with a couple of cycles.

PULL THE UNIT OUT AND CLEAN THE CONNECTOR CONTACTS WITH A RUBBER PENCIL ERASURE. PUT IT BACK NICE & TIGHT, WORKS GOOD, LAST A LONG TIME! BEEN THERE, DONE THAT! LATER.
P.S. I'M TALKING ABOUT THE DISPLAY PANEL ITSELF.
