Rayo has been kind enough trying to help me with this problem but maybe someone on here has had a similar issue and found a solution. I have the relays for the low and high side fan wired correctly but the fan still doesn't come on at temp. I replaced the ECT sensor hoping for an easy fix with no luck. The computer IS receiving signal from the ECT sensor verified with my volt meter but the low speed pin is only putting out 1.5 volts once warmed up. The high side is 1.5 volts ALL the time but it never changes with temp or A/C turned on. Right now I have the high side wired so it comes on when the key is on but I'd really like for the fan to run off the computer for that factory install look. Not likely that I got a bad computer is it!? Hope not! Thanks for any help!!
