Electrical problem 6 cyl Front Wheel Drive Automatic 183550 miles

The AC/Heater blower motor runs all the time even with ignition off. Had to remove 30 amp fuse in engine compartment to shut off blower motor. Electrical diagram shows 30 amp fuse powers a blower motor relay. Found 6 relays under the fuse bank in engine compartment. With 30 amp fuse reinstalled disconnected each relay one at a time. The blower motor still keeps running. Could not find any more relays in the engine compartment. Please tell me where the AC/Heater blower motor relay is.

Thank you.

It sounds like you have a relay stuck on, here is its location so you can remove and replace it.

Hello,

I have seen where the fan speed control module will short out causing the fan to stay one as well. Here is a diagram that will show you where it is.

Please let us know what happens.

Cheers, Ken
