i've been having cooling fan issues for a while now. i'm stumped. i have mine rigged to run by bypassing the a/c low pressure switch and unplugging the compressor. this works for now however i would like to get them to run normal. i've replaced both fan relays, resistor between the fans, line to the resistor, and cht sensor. what should i do/check next? i have only the haynes manual to go by so any/all help is appreciated.
