Need under hood diagram for fusebox/relay. 99 gmc yukon only the one under the hood. thank you.

The back glass release relay on a 1993 GMC Yukon is located in the fuse box under the hood of the vehicle. The exact location of the relay is usually indicated on the inside of the fuse box lid.

To find the back glass release relay, first locate the fuse box under the hood of your 1993 GMC Yukon. Then, locate the relay diagram printed on the inside of the fuse box lid. Look for the relay labeled "back glass release" or something similar.

If you are having trouble locating the relay or if it has burnt out and needs to be replaced, it is recommended that you consult the vehicle owner's manual or take your vehicle to a qualified mechanic for assistance.

fuse relay box should have diagram or legend on the cover that will give you fuel pump fuse and relay locations.or look in the owners manual.

If your A?C won't shut off, it isn't a fuse. I would tend to look at the switch.
