My dash has been flickering for months and I thought it just needed rebuilding. Well to make a LONG story short, broke the clip for my Alt connector and ended up killing the battery. Replaced the clip and battery and low and behold the flickering was gone.

Moral is that when your dash starts flickering, it could be telling you that your battery is heading south.

Default How about hvac controls?

Thanks for the tip about the dash, I will have to store that one away somewhere. Never had a problem with the dash per say, my problem is with the electronic HVAC controls. The car is an 87, I have pulled the dash 3 times now to ensure all the connections where tight/functional. Anybody got any ideas? I'm not going to say that it is driving me nuts, but it is starting to **** me off.

thanks,
James

Take off the control face and clean all the button contacts, I did this and they work good as new.

Mine flickers every now and then even after a new battery. I think it is the voltage regulator heading south.

My LCD had been flickering a little with the lights on ever since I bought the car. This spring, while I had the engine out and was cleaning everything up, I cleaned up every ground connection and coated them with dielectric grease. Haven't had a problem since.

Weav's vet is right and so is pianoguy. Here's how to tell the difference, if the dash starts to flicker, look and see if the parking lights are doing the same thing at the same time. If they are then it's most likely the regulator, if it's just the dash itself then it's probably the contacts.

On my 91 I removed the cap and rotor and plug wires. Un plugged the wiper motor connections and was able to get in with a long socket extensions and 1 u-joint. Yours is no doubt slightly different but should be similar.
