Quirky Fan speed Controller
:confused:
Greetings,
My 95 LT1 'vert has a disfunctional fan controller and I need your help diagnosing it. It seems that when the outside temperature is below 70 degrees I am able to raise and lower the fan speed with the two arrows on the climate control panel just fine. But, once the temperature goes above 70 I am only able to lower the fan speed, and not raise it. Sometimes I get lucky and can hit the auto button for the fan, which takes the speed up to 10, and then I can back it down as needed. But most of the time I am not able to raise the fan speed either by the fan up arrow or by the auto fan button.
In addition, once the fan refuses to increase in speed, I am usually not able to lower the temperature with the decrease arrow button either, but I am able to increase it.
What is going on here????

Re: Quirky Fan speed Controller (Ultrasonic)
I have the same problem ,I find that when it happens ,I push the temp hot and cold buttons together its works, Disconnecting the battery for a few min. then reconnecting sometimes works. If either of these don't work you may have to pull the controller out disconnect,clean the contacts ,and that should work good luck Jim.
