I have a digital display that wont come on at all, but all the press buttons are lit up like it is getting power. No heat or AC without this unit working. Went and got another from a 1995 that looked exactly the same. I installed it and the same thing again, buttons lit up but digital display gets nothing. What can I do?

Hey FRANKIE,

It sounds like you need the programmer under the dash, this was a common problem with that car. Check Ebay for it, "Climate control Programmer" is what you are looking for.

Please let us know what you find so it will help others.

Best, Ken
