I had the same problem, disconnect the battery cables and check your cabin filter that's what usually cause it. It should start back working once you connect the cables but make sure to check the cabin filter and replace if needed.

Where is a fusible relay located on a 98 grand prix gt?

there is no such thing as a fusible relay, there are relays and they are located inside the car some under the dash on driverside and some on the pass/side and then there are relays under the hood in engine compartment inside the fuse/relay box, this acar also has a fusible link or two, this is like a peice of wire but inside the wire will blow like a fuse and the only way to test is with a test light you would need to see if power runs the lengh of that link wire, these are located by the battery and then in the fuse /relay box and on the starter sometimes, the ones in the fusebox under the hood may also be metal type, heres a few picture to show you a few types of fusible links,johnjohn2_51.jpgjohnjohn2_52.jpgjohnjohn2_53.jpg

When i turn on the wipers ,the heater blower goes

Look in the fuse/relay panel under the dash on the drivers side for a blown fuse controlling wipers. Also look under the hood at the fuse/relay panel for a blown fuse controlling the a/c blower motor. Look under the covers of both fuse/relay panels and it will tell you were the proper fuse or relay is located in each panel. hope this will help you.

Horn on 99 Grand Prix stopped working. When pressed, I hear NO clicking or indication of action. I replaced the fuse. No Luck. Don't know where to look for the relay.

On a a 3.8 grand prix, the relay is under the hood, I think its number 16. It has the fuse and the relay. You can swap the relay beside it and try it. If it works then replace the relay, if it doesnt its not the relay....but thats where the relay is located.

Heater stopped working on a 1994 pontiac grand prix

look in the glove compartment on left hand side should be a little door. if not it would be under the dash board by the brake peddle. if not there, look under the hood for the relay.
