Everytime i drive my 86 ZX down the street the damn climate control starts clicking. I've narrowed it down to a series of what look like relays just above the gas pedal. They're connected to a series of what look like vacume lines. When it clicks i can actually feel it when i put my hand on them. If ANYONE has ANY info i would be extremely appreciative because its driving me up the Gaddam wall! ThanX

 

I too would like to see some info on this problem.

 

Start by replacing the vacuum lines. Both behind the dash and in the engine bay. Especially troublesome is the line that runs through the firewall. If that doesn't fix it, you'll need to replace those solenoids.
