The relays are located in the engine bay inside the black plastic box that should be marked "Fuses". When you remove the cover look on the underside of it and there is a diagram to help you locate the relay you are looking for. Please rate me on my answer.

2002 chevy Blazer 2 door. Power locks,and liftgate stop working.The locks will engage when I shift to drive and will disengage when placed in park. Where do I start?

Plz explain...are the locks supposed to lock/unlock when you put the car in Drive/Park, or not?

Does the lock/unlock SWITCH on the DRIVER'S door work/not work? If applicable, does the PASSENGER's door lock switch work?

I'm not getting power to the fuel pump,it is a 2002 blazer 2 door, the only way I get any power to it is if I manually touch the points together in the fuel relay switch other wise nothing, do you ha ve...

If by manually touching the relay points give you power to the fuel pump , i would assume that your relay is bad on the power side.

try to exchange the relay with one other of your fuse box . If it works fine with other relay change the relay and you'll be on your way.

Just for you to know!!!

Here is how a relay works you have a driving side and a power side . the driving side is in fact an electrically operated switch that when current is apply closes the switch that is on the power side.

Test your relay by asking somebody to put one finger on the fuel pump relay. when you have power on and of on the driving side of the relay, the other person will sence that the relay is clicking . if it desn't change the relay cause it's burnt on the driving side. if it does and you don't have power to your fuel pump chnage the relay cause it's burnt on the power side.

Flasher relay is clicking when signals are not in use?

Those are the typical symptoms of a problem with the mutifunction switch. The dielectric grease becomes impregnated with metal flakes, which jumps the contacts inside the switch. The clicking that you hear is the flasher relay located behind the glove compartment. Replacing the switch is not that hard for a DIYer. Some guys have remedied the problem by taking the switch apart, cleaning out the old grease, and applying new grease.
