No power to windows, AM/FM Radio, or mirrors.

If I remember right it was number 21. I know it is that row; R20, R21, R22. That row is closest to the windshield. According to my records the part number 8084620 or C07D05; one number is the dealers inventory number and the other is the part number. Sorry, I can't remember which is which. With a fleet discount we paid $8.35. It is a black 1"X 1"X 1" cube. Make sure you match the blades. The first time I went to the dealer they gave me the relay for the R2 position; it is a different amperage and the blades are situated differently. The way I knew I had the correct relay position is by turning on the radio and then pulling the relays one by one until the radio went off. I am 99% sure it is the relay at the R21 position for my truck. Yours may be wired differently. Hope this helps.
