Rad Fan Will not Shut Off

["Parry, John C" <John.Parry@Unisys.com>]

Hi List,

Has anybody had any experience with the rad fan running continously on high
speed? Car in question is an 1989 Audi 100. My climate control is screwing
up and while I was trying the A/C mode the rad fan came on (on) high speed
and now won't shut off. I know the fan should run at reduced speed when the
A/C is selected.
This happened yesterday on the way home from work. This morning when I
started the car (outside temp -02c) the fan again started on high speed, CC
set to Econ. I'm thinking it may be the resistors or the rad switch. I
removed the relay to drive to work and that shut off the fan, I thought I
would be able to turn the fan on by selecting the A/C but that didn't work.

Seems like with the warm weather here the car is making me work outside!
(replaced inner and outer L/H CV joints last Friday in driveway!).

By the way thanks to all for the responses to my CC problem. Will have a
look on the weekend.
