1994 Mark VIII - Cooliing fan and A/C compressor don't come on

[tgs1964]

My cooling fan and A/C compressor won't come on. I replaced the VCRM and still nothing. Any ideas?
Also the turn signals work but the emergency blinkers don't. When I turn on the blinker switch, the turn signals and the brake lights quit, but the third brake light still works.

Did everything happen at the same time? Could be isolated incidents. A/C compressor won't come on because your fan isn't working. Question is why is your fan not working? If everything happend at the same time, Sounds like you definitely have a short circuit somewhere. I'm not the best when it comes to electrical crap but that's not my dept but be very careful.

Yes, happened at the same time.

Emergency blinker problem was the switch.

Is your cooling fan locked up? Common problem. Reach down and see if you can turn it by hand.

Yes. tested the fan and it works.

Turns out that it was the cooling fan motor going bad. Would still spin when tested, but was pulling too many amps for the circuit that it's on.

Thank you for posting the problem. Glad you got er figured out!

 

[dnsherrill]

so it was blowing fuses? what makes it surge/pull too many amps? worn out bearings?

Do you need a good cooling fan? I've got one. $75 shipped.

shorted/broken winding. degraded internal wiring. something causing an excessive voltage drop somewhere. usually something like that.

No, wasn't blowing fuses. Just not enough amps to spin it. Chris2523 pinpointed the reasons.

Thanks for the offer, but already have one.

Cooling fan motor shipped NEW from rock auto....$76.50? Maybe used $30. Are you talking about the fan or the motor?
