it should be under the hood, there should be a black relay box .
maybe long and thin near the the battery .
or on one of the fender walls , and the cover should tell you which relay it is,k....
not fuses or relay?
The blower motor, or blower motor relay is probably out.
There could be a ground on the body of the vehicle. If this isn't the case there could also be a problem with the relay that go to the indicators.
Checked the fuses. Tested the horn, direct connection to the battery. Check horn relay. Here is the basic. Between the horn switch and the horn relay is the Clockspring Assembly in the steering wheel. If you ground the red/green wire at the base of the steering column and the horn works, you have either a bad horn switch or Clockspring Assembly.
Left and right stopped working? Check the fuse and/or the flasher relay. Only the left or the right stopped working? Check the bulbs.
It's the relay. Check the relay box behind the fuse box or the fuse/relay box in the engine compartment.
Replace the Turn Signal Flasher Relay.
its probably a bad multi function switch
fan relay or fuses not working properly, probly the relay, you can straight witre it to find out
The expedition door lock relay could be stuck causing the grinding noise. Check to insure that the lock relay is working properly.
check your fuses. check the bulbs. maybe replace the turn signal relay Check the fuse box. The fuses may have blown it is very easy to do and only costs about 20cents to buy a new one.
it could be the horn relay fuse located in the engine department with the other fuses.
