LCD display In my 2002 pontiac grand am, the LCD display on the stereo is dim. you can't read the time or anything. i tried changing the fuses but nothing seems to work. is there a light bulb or something that may be out?? Help

popping noise or clunk could come from cv joint of front axle shaft
and look if back plate of front wheel not touching the rotor
for electrical problem to say without seen it but I will check ground or bad connection to headlight switch (burn connection)
if there is no bad connection at radio the radio display dim come from the headlight switch and dome lamp rheostat
hope it helps

Get a wiring harness connector for your 1998 GM car - THEN carefully follow each wire color on the harness. Do NOT connect anything to the GM orange wire except "Memory". Do NOT connect anthing to the harness for "Lights" or "Dash" or "DIM" - you will blow fuses. Only connect the Power, the memory and the speakers - period. Then you'll be safe.

I can't answer because I have other question open, sorry, but here I send any comments and clues to solve (I hope).

For the FUSE PANEL, location and description, I suggest check the 2000-Pontiac-Grand-Prix-Owners-Manual (page 330 and next). A/C have one "diode". Check it.

About your radio display, sound like a internal problem, keep in mind that the CD is working.

The Security Litgh, its possible that you have any problem with the THEFT system or any aftermark alarm (if you have).

I had the same problem with mine and my 2004 Chevy Silverado. Gm is making the cars so that have to buy the quick connect harness for it to work. All the chimes, idiot lights, electric read out is all through the radio harness, so you can not cut and splice any more. These harnesses are expensive too. Best buy is price at $120.00 for the Grand AM. My truck was $115.00. Its F****king rediculous!!!

If your talking about the stereo preset station than it had nothing to do with the oil change. There's a myth that every time someone gets an oil change and they drive away and a problem comes up immediately it has to do with the oil change. An oil change is a drain of oil, change of oil filter, and then fill new oil. Your stereo has absolutely nothing to do with the stereo. It seems like the stereo got an issue. I hope this help.

clean the computer lead interface. my buddies car did the same thing, we cleaned the computer leads with a good eletronic spray cleaner and it fixed the problem.

I just bought the haynes book and here is what it says,, when the owner is restored to the stereo the stereo wont turn on and LOC will appear.. here is what it says.. ... turn on ignition switch but leave stereo off
Press MN button.. 000 should display ... it says that in 2002 two an dlater models
that it will learn a portion of the VIN number fo your vehicle.. so you will just have to try those numbers until it works.. syas that you press the HR button until the first one or two Numbers match your code.. Press AM/FM button SEC should appear indicating the stereo is unlocked.d. if LOC appears the numbers arent correct.. try again..

Fuses are either bad or good no in between. Bulbs are the same way. You've got a dead short in your wiring most likely. Get that fixed or your car can burn up. No kidding. Could be a failing radio drawing way too much for the wiring size.

Check at the headlight sockets for a bad ground.

replace fuse or relay to the park lights .
