Fan Motor question

[Tom Schindler]

My wifes Explorer is having an intermitent issue. The blower fan sometimes works and sometimes doesn't. This is the 2nd time it happened. The first time, it was warm outside. It started up after a few seconds. We went on a trip for the week in the trac and let the 2K Explorer sit for 11 days.



We get into it today and go to leave. The fan did not want to come on. It was not until some hour later, the fan started working. It has been cold and wet this week and was very cold today.



Any experience on if this is the blower motor or the swithch/relay? Blower motor is cheap and with over 214,000 miles on it, it is quite possible the motor is heading south.



Any experience with this type of problem?

Intermittent electrical problems suck. Good luck.

Next time it won't blow try giving the blower motor a loving tap and see what happens. Typically when the blower motors work intermittently it is either the blower motor itself or burned wiring at the resistor.

Thanks L1tech.



This is something I have done to starter motors. Make sense that it would work for a blower motor.

Caymen,

You might want to jiggle the blower control knob. Sometimes the contacts get dirty and get a hit or miss connection. But changing the blower motor resistor would probably be much easier..:grin:

Also check the contacts on the resistor block, Common high mileage ford problem...

Everything is working flawless now. Go figure. We have to wait until it does it again.
