How hard would it be to convert a manual climate control to digital?

Also, my heater does not seem to be working, nor does my rear defroster and the fuses are still all good. Any ideas? Thanks!

 

craig brace has a write up, you have to have the unit itself and a its sensors, a pain from what i read

as for no heat, sounds like the heater core is bad......have fun with that....have to basically remove your entire dash to get to it

 

if you're doing the swap you may as well do the heater core at the same time, half the dash comes apart for the swap anyhow

 

Sorry to highjack this thread but im a newbie & could not start a post as of yet (trying to get 15 post first). Here's my problem that is somewhat connected to this. My light on my digital climate control (93' GXE) is sometimes lit (supposedly it should stay on) but most of the time its not. Does someone here have the same experience?

I have just bought this lastweek so I am still not familiar with this car.
