I had my heater core replace on my 94 Audi 90 and when I got it back the cruise didn't work. I have the Bently Audi disk for repairs and parts but it is vague. I can't find the Cruise Control control box. I want to check to see if the fellow that repaired the car (he has moved out of state) left some wires unplugged. If anyone has any Ideas I would appreciate hearing from you. It worked fine before he fixed the heater core.

entire dash removed for heater core/AC evap work; to include some exterior cowling from under hood...
most common problem is elongated relay jostled and/or unplugged in the "fuse box" under hood, near driver's side firewall...
hope this helps: ctesla@trip.net
