well had to swap a new ls into my car and now the fan wont kick on and the thermostat doesnt seem to be opening, ive tried bleeding the air out of the system but its not working either. when i jump the fan switch the fan works but wont kick on when its plugged up. i swapped it out with a known good switch and still nothing. also swapped out the thermostat for the one out of my old ls that was working and now it wont open either. guess il have to buy a brand new t stat but the fan issue i cant figure out. maybe the relay?
