Is the temperature display blinking on the electronic climate control unit?

OK, to solve your problem you need to have the HVAC scanned by the dealer to get the HVAC code. That will tell you what is wrong.

That sux - the dealer has to scan it????? They charge $80 to do that.....

I have the same problem with my 92 SSE. temp display is blinking and it blows hot air.

Does anyone know the cause of the blinking?

Not for you my friend. The 92-93 models can be done inside the car.
