SOURCE: power steering fluid on grand prix

You should add it to the power steering pump reservoir, which if you have the 3800 series II its behind the engine on the passenger side.

SOURCE: srs airbag light is on on my 99 pontiac grand prix

If the seat belt light comes on intermittently with the belt buckled, it may have a bad switch in the buckle or a loose connection @ the switch. This may also set a diagnostic trouble code in the srs control module & keep the srs airbag light on.

SOURCE: I want to disable XM radio and OnStar on my 2005

I have disabled factory xm/onstar units from many cars with no issue. i believe the onstar/xm units are both located in the trunk of you car behind the carpet (usually labeled accordingly). If you can find the fuse dedicated to the unit you can pull that. I have found the fuse is sometimes located on the unit. If you cant find the units then you can pull out the radio and unplug them from the back (more often than not it will be the smallest harness coming out the back). A quick way to test... have your car on and pull one plug at a time... make sure, once you have located it, test you audio (some harnesses are for amplified audio systems). The only neg. effect i have seen (rarely) has been the loss of the door chime.

I have a 2005 pontiac grand prix. I just bought an after market radio. I don't know the what the wires do in the stock wiring harness. i can't figure out which color wire did what function


Well you can start by checking the wires behind the speakers. There are almost certainly 8 of those. Then there is a power wire which ought to be red and a heavier gauge, plus a ground, which should be black.

Or you can just refer to this wiring diagram :>)

I have a 98 grand prix an I was wondering how to install it.. I have a harness that came with it but my factory harness won't fit. I was wondering if j have to rewire the factory harness to my JVC...


You need to go to your local "best buy" or electronics store and ask them for your car's "stereo wire harness". This will convert the wires from your car to match all the colors from your deck. (green, purple, white, gray, blue, yellow, red, ect. Same on all after market decks. All brands use the same wires) Take that new harness and your deck harness, twist the matching wire colors together, tape them with electrical tape, plug the harness back into the car and deck, and it should be good. Click, click, done. Remember to plug the antenna in as well before you get the deck in.

What years 3.1 engine will fit in 1998 pontiac grand prix


Unfortunately it's a (relatively) one year only engine (without major component changes). However, these will fit without those changes:

'97, '98, '99 Buick Century,

'98, '99 Lumina (car),

'98, '99 Grand Prix,

'99, Monte Carlo.

This is assuming that you have an (8th digit) "M" VIN. Off the top of my head.
