theres a write up for an over ride switch so you can turn it on whenever.

Not really something I'm into, or familiar with...I noticed in a recient "heat soak" thread there was some mention of TSB's and a reprogram for the puter' to change the way to fan comes on...$150 was mentioned there IIRC. That had to do with fuel system stuff getting hot. If it's working fine I might just leave it. I don't think the metal cards allot about the difference between 212* and 218*....

make sure everythings still hooked up properly for the ecu according to those diagrams in the writeup. my nephew deleted everything but the power-> switch-> fan and killed his ac because the sensor wasnt going to the ecu
