Hey everyone !
I have a 98 C5 convertible ... I currently have the basic 3-dial hvac unit.
Its not working properly anymore... the dials sorta just keep turning.
I was hoping someone would be able to tell me if the other model hvac will work in a swap ... I'd like to put in the model that has the digital temperature reading and the driver/passenger dials.
Will that model work in my car ?

THANKS IN ADVANCE EVERYONE !
Brian

Sounds like you may need some new *****. The rotary controls are available to replace the ones in you car also if those are bad.

Would be great if it were as easy as just swapping the dual zone unit for the base one, but unfortunately I think it is a lot more complicated than that. I do not recall seeing a thread where such a swap has been tried. If it is just the ***** that are the problem, hopefully you can find a replacement set and solve the problem.

Do you or anyone know of a source to purchase just the 3 *****? I am diligently searching and coming up with nothing so far. Plenty of replacements for the 2 **** controls. TIA.
