I believe the fuel pump relay is the first one on the left. The other two are for the horn and the day-time driving lights.
Power seat relay location for 1996 Blazer
Take out all the junk in the glove compartment and look in back. You will see a door marked "relays". Remove the door and the fuel pump relay would be the first one on the left.
Where is the location of fuel pump relay on 1996 Chevy Blazer?
if there is not a key hole you cannot lock it.
I believe it is in your glove compartment there is an access to your flasher.
In the fuse panel
under the hood in a big black relay box on drivers side
The high-speed fan relay in under the hood on the firewall left of center. If I remember correctly, there are 3 relays on the 1996. The relay closest to the passenger side is the high-speed relay. I had to replace it twice in my 1996 blazer You will propbably find that the plastic is melted slightly
Fuse panel should be located on the drivers side between the door & the instrument cluster. There is also 3 relay switches located behind the back panel of the glove box.
Behind the glove compartment.
The relay for the vehicle is located in the glove compartment in the very back. There may be a black plastic cover over it so you will have to look carefully. I believe this is right. If by chance I am wrong, check with the dealer. Good luck.
Fuel pump relay, horn relay, daytime running lights relay and if there is a fourth, power door lock relay.
