I have a dual electric fan
I just took my thermostat out and drilled two small holes in the stat and put it back in
When I was driving today my fans would not turn on and my truck got up to 220, thermostat is a 160, the intake manifold is where the sensor is, Im not sure why the fans are not coming on, I looked for a fuse today but could not find one, Im assuming power is not getting to fan somehow, cause Ive never had a issue like this and I know the thermostat has nothing to do with electrical. Maybe underneath i may have kicked or disconnect the power somehow.
As a side note I drilled out stat last week and the truck and fans have been running just fine till today.

Question , can I bypass a fan relay and make the fan work with a on/off switch and get it to manuel somehow, Im sure its a easy fix???
