Climate Control Module Repair

Hello all my name is: YellowDog
I have a: '91 Stealth TT
It has the following issue:
Climate control display not working. Capacitors, Diodes and IC3 are looking bad. Has anyone replaced these parts successfully themselves? Any issues I need to look out for?

Here is a good source of info: Electrical: Replace ECU, ECS and Climate Control Capacitors - 3000GT/Stealth Wiki

You’ll read about the caps and a particular diode that usually causes trouble.

I’ll note that I replaced these on one of my two, and it was unsuccessful. I then used a service advertised on eBay and they both came back perfect.

yes i had same issue , there is good info on google , not to bad a job
