I got in my '02 F-150 after my sons baseball game today - and the A/C fan wouldn't blow. I can feel cold air coming thru - but the fan is dead.

Anyone have a hint where I should start? I'm guessing the fuse in the Power Dist. Box... anything else I should check?

Thanks, Chad

 

I would check your fuses and relays under the hood first, had that happen on a friends 02 ram once. One i think 20 amp fuse later and all was good. Hope this helps.

 

Check:

Fuse F24 in underdash fusebox (10A)
40A fuse underhood fusebox (#105)
Blower Relay - above gas pedal under dash
Open resistor pack (in dash) (has an internal thermal fuse)
Faulty fan speed switch

If you have a meter, gain accecss to the blower motor connect and measure DC voltage at both pins with the ignition in RUN and the HVAC system ON.

If you measure battery voltage at both terminals, go for the last two items on the list.

If you measure no voltage at the terminals, go for the first three items.

There's a couple other things, but these are the most likely.

Another "safe" ford idea. They put a 40 amp fuse to feed the 30 amp relay? Ususally the relay goes bad first. If the relay holds out and doesnt fry out, the switch goes bad and sometimes catches fire. Very common in Econoline vans were the put a 50 amp fuse to feed the 30 amp relay.
