blue98ls1 Posted August 9, 2017 Report Share Posted August 9, 2017 (edited) My 87 firebird (tpi car) has a problem with one of the cooling fans not coming on by itself (dual fan setup). The one fan does with the A/C the other one that is supposed to kick on once it starts getting really hot doesn't. Fuses are good. Relays are good (new one installed). The fan can be triggered manually to come on at the relay. I have replaced the coolant temp sensor and switch. We temporarily wired in a toggle switch to kick it on in traffic if needed, but i want to fix it right. I am out of ideas.
