Re: temp warning light - please help

["studentper" <studentper@email.msn.com>]

    i checked the coolant level and its fine. unplugged the sensor switch
under the resevior, and the light still goes on after a cold start in about
30 seconds.  i assume that this sensor is the only one that would care about
the mixture of coolant/water?  still trying to figure it out, any
suggestions appreciated.
    also, anybody have any ideas about the fan and a/c problem?  i'm
beginning to think if you fix one thing the rest of the parts get
ealous.  --bryan '88 90q
