automatic temp control problem......

[designeraccd]

Last night we took our newly purchased 2002 coupe (33k miles) out and as it was lo 50s turned-or tried to-the heater on for the first time. I assume from looking at the controls and the "explanation" of use in the owners manual that the small "black" window should light up with a display, for example a temp. setting. NOTHING is visible in that window. Also there is no position indicator line on the driver's side temp control knob so I can't tell what I'm "aiming" at from that either. Am I missing something or is something amiss?

I sort of got luke warm air to blow, windows up. BTW when I tried the a/c b4 buying the car I rapidly got cold air but didn't notice the lack of a display. Input, advice??? TIA....DFO

The light display in the C5 heater conrol unit is prone to failure. I had the whole unit replaced once. I have heard of people repairing the light, but this is not the factory approach. Try a search of the threads. This has been discussed before.

Try a search on a/c head unit. It will turn up a number of things.

Good luck!

Thanks, I did search but only came up with a price of @ $700. Not sure if that is parts only or parts + labor. Either way...owch! Next ?....can it be converted to the "standard" htr. a/c controls and get rid of the mickey mouse gee whiz, failure prone electronic gizmos??? Let me rephrase that: can it be done without tearing the car apart and costing even more $$? TIA DFO

look on ebay under corvette parts. I bought a replacement unit from a guy there for 100.00 and it was easy to install and works great.

The loss of the display LED is a common problem. Here is a link to
another forum that has some good info if you want to remove the display
yourself.

The problem is in the soldering of some connections on the back which are not done well from the factory. In this thread is a link to some detailed how to instructions on removing and replacing (with expandable pictures) the display,as well as a link to someone who fixes the boards reasonably.

Hope this works & helps you.
