- 99 VT Commodore Executive
I recently purchased a 99 Commodore VT Executive, auto, v6, etc..
The low speed fan relay was missing when I bought it, and i bought one and put it in.. I now see why the relay was missing - it stays on all the time.
The high speed fan operates properly, turning on when it gets hot or when the a/c is on. It cycles normally as far as I can tell.
However the low speed fan stays on all the time, even after the car is shut off.
From my searching in the forums, I gather it might be two things - either a bad ecm, or a bad coolant temperature sensor. Does this sound like a fair diagnosis? The temp. gauge on the dash works properly, and I recall reading that there are separate sensors for the gauge and the fans....
Any advice?? I don't want to pour too much money into it.
