Hi Adam,

It's easier to pull and resolder the joints on the CCU on pre-88 SEL's. The later CCU units don't allow full access to all the circuit boards, the earlier one's do. If you do a search on climate control you'll find threads with photos of each step. Also check the DIY section.

Good luck!

Bill
