See if you are getting voltage at the relay when you turn the AC on. Check your wiring and connectors before replacing PCM, I doubt that is your problem.
Check to see if it is getting power - if so could be bad fan motor - if not check fuses, relay, and temp sensor

Jeep does not have one could be the relay or bad pump.
Could be bad fan relay?Could be a plugged or restricted radiatorCould be a bad radiator capCould be a bad thermostat
Under the hood there will be a fusebox....also there are relays. If you can hotwire the fan to run, the relay is probably bad. There is also a collant temp sensor to check out if all else fails. It is located by the thermostat housing.
The 1998 Dodge Neon does not have a relay. It does have a blower motor resistor that could be bad.
how do i tell if my relay is bad ?
They are designed to work when: A/c or defrost is on Coolant temperature exceeds 235 degrees Bad sensor? bad cooling fan relay/module
a bad relay-a bad temperature sensor.a blown fuse.A bad Ground..a BAD power Source.A COOLING FAN MOTOR THAT IS BURNT UP. a bad ign switch ---A DEAD BATTERY.etc-etc
Inoperative cooling fan(s) Bad thermostat Bad fan switch sending unit Bad fan relay Blocked radiator cooling tubes (internally)
Bad fan motor? supply 12V hot to see if it works - if not bad fan motor Bad relay? Bad sensor?
The fan sensor is bad or the fan relay is stuck. Swapping out the relay is the most likely fix.
yes, and the best way to determine if one is bad is to just switch it with the horn and try to honk it. if it honks, then that relay should be fine. my car would not turn on the other day due to a bad relay so i switched it with the horn so it would start and it got me to the auto shop.
fan relay, bad connection at wiring harness, bad fan, bad coolant sensor, bad electrical ground, likely causes
cooling fan relay is bad?
There is prob a bad relay that's not triggering the fans to turn on.
Could be the relay or bad battery cable connection at the battery or relay.
