[s-cars] climate control issues

[David K. Blumenkranz]

hey everyone,

i just got back into town...
long overdue vacation.

i am having  issues with my temp control in my dash. sometimes the
buttons work, and sometimes they don't. They seem to not want to work
from time to time, and if i really push hard it "might" work.

i was wondering if this might be a problem due to a rubber piece
inside engaging a button or maybe it's directy.
if i had to replace the entire control unit...how much do you think it
would cost, and is here a way to open it up and clean it out?

any help would be much appreciated.
