HVAC Controls - No display.

[Haitian_King]

Today for the first time (to my knowledge), my temperature display wouldn't come on. I pressed AMB and nothing showed up. I turned the fans on and they came on. Later, the display showed 90 when I tried it again. I tried it again later on this evening, and the samething happened.

At first I thought it was because of the ungodly temperature of my interior, but tonight was substantially cooler. What would cause that to happen? My Q has 86,000 miles on it. Is it time to replace the unit?

Probably. Search on http://www.jerrytucker.net and display.

The typical failure mode is that the whole display blacks out, but everything still works... sometimes tapping on the dash will bring it back for a few minutes.

The problem is not a loose connection or bad capicitors. I tried resoldering every joint, and replaced all of the capicitors with no difference on my controller. Jerry replaces a component on the board, but I don't know what.

Thanks guys.

Check back with me in a week or two. I may have a working one for sale.

[Haitian_King]

Yeah. I did what you guys said. After hitting it a couple times, it registered at 85 degrees. Glad to see that it's not a MAJOR malfunction. But, it is quite annoying.

And it won't get better, but will fail when you most need it.

Grrr. The damn Q. Beautiful to look at, a pain in the *** to maintain.

Mine gets funny sometimes too. What mine does is the temperature reading on the screen starts to run wild. Here is a link to a quick video I made to show you what I mean:

If the video doesn't work and someone has another way to host it, please let me know.

And temps are to hit triple digits tommorrow, and my work shirt is a black polo. I'll be driving a black car with a mostly black interior. I hope i don't die of heat stroke

I've seen a few in Texas. Very few.

Well. I survived. It was like a wet blanket. The humidity was TERRIBLE. The interior of my winshield developed moisture and I had my windows down and sunroof open this evening. Crazy right?

My damn AC worked in January when I bought the car, now when I need it, it's busted. Stupid Murphy and his law.
