Hi All.. I am writing on behalf of a friend of mine who has a 1992 100 sedan. He feels his A/C controller head has "shot craps". The display has gone south..... Any Ideas where to get a good replacement or can the current one be repaired / rebuilt? Thanks in advance for your usual help! Ron Husak 83 UrQ 98 A4 1.8 Tq (son's) Soon to have 91 200 20 Valve....
