Where is the relay switch located on 1997 gmc jimmy?

Excluding drl and fog lamps, there is no relay. The voltage to headlamp switch, hot all the time, I didn't check for fusible links? The voltage from headlamp switch goes to dimmer switch then to headlamps, at the headlamps check voltage and ground. My info showed sealed beam or quad lamps, I didn't look at both.

In the glovebox, behind the cover that says relays.

The starter has a relay, not a fuse. Check your owner's manual. Switch the starter relay with the headlamp relay or another relay that is the same and see if that works. If it does, you have a bad relay. Get one cheap at pick a part/

sounds like it replace this..

LOOK AT LEFT HAND SIDE NEXT TO DOOR SIDE PANEL

fuse in the fuse box. also the power to prime the pump starts at the oil pressure switch. check that out too. then the relay for the pump in that order

Fuel pump relay is in your gluve box. I belive there are three relay's there and it could be the middle one. Getting old memory bad LOL.

I believe it's the middle relay in the glove box. You should feel the relay click on when you turn the key's, but you only have 2 seconds.

The main relay switch is on the fuel pump itself/ There are others in the engine compartment and under the dash or side of dash panel

in the steering column attached to your blinker arm.
