My power windows don't work in my 2004 mountaineer only my sunroof nod it's not the fuse. What do I do ?

Here is your answer from Just Answer. Exactly the same issue and caused by the 'RAP Relay' (Retained Accessory Power).

It is located in the Passenger Side Fuse Box.

Is the motor receiving power? If not you have to check electrical system to locate the place that is not transmitting power. Could be a fuse/relay, switch, bad connection.

If the motor is turning and nothing happens then the drive mechanism from motor to sunroof is stripped. Not good.

Cud b a fuse, bad wire or amodule. May need to test fuses w a lite. The othr two may need an xperiend mech not a dealer. Find one at surecritic.com

Fuse,Switch or Control Knob,Mirror Motor or Module
if one applies

Don't know if you can control or check with a scanner
I would have to look at my software to see if ford offers that

I had the same problem. I found a wire in the drivers door was shorting. The problem was it was not a complete short and giving good readings on a test light. Use a volt meter and have fun tracing the wires.

Hi, it is likely you have burned fuse 17 in the fuse panel by the driver's left knee.

they can go bad-swap it out with another that you don't need, just to try and see if it is the relay-listed are relays that might only control, for instance, the rear window defroster-generally, relays are all the same, some just get used heavily and some don't (i.e., ABS)-worth a try

fuses this size are usually under the hood on the drivers side fenderwell , black square box, possibly a hand type screw holding the cap on, not really a way to test these fuses other than to find one of a similar size in the fuse panel of a known working circuit and swap it with the power window fuse temporarily to see if they work

check all the fuses 1st ...also ensure the battery is charged ...more than likely fuses from a possible short let me know if the fuses are in fact blown and we will proceed from there

Check the fuse under the hood top right corner fuse box Third fuse down on the left side It is a 30 but in older Mercury Mountaineers the wires come slightly corroded and tend to not transfer enough power. So in conclusion either A: the fuse is blown or B: Boost it up to a 50 fuse which is what I had to do
