Pontiac Grand Am Maintenance & Repair

  • Drive in to any Quickie-Lube, and for $20, you get an oil change, and they check all the fluid levels.
  • Vehicle: 2002 Pontiac Grand Am LE, Manual Transmission, 2.2 L4
    Problem: The "Brake" light at the top of the instrument cluster is always on.
    Cause: Apparently, the parking brake light switch is out of adjustment.
    More Information: Most of the time, while I'm driving, the Brake Light on the dash is on. Ocassionally, it will go off and stay off for a couple of miles, then come back on when I make a left turn. I'm pretty sure it's because the parking brake electrical switch is out of adjustment, or the parking brake cable is not returning all the way.
    Does anyone know where this switch is located and how to get at it I assume it's hidden somewhere in the center console near the park brake lever. I'd be grateful for any help.

  • Hi Costa Rica Dick. Sorry I cannot help with the parking brake switch location but, before you go tearing the console apart to search for it, please check your brake fluid reservoir levels under the hood first. The fact that the light can come on or off with the centrifugal force of a turn suggests that you may be low on fluid and making intermittent contact with the sensor as the fluid sloshes around. Topping off the fluid reservoir(s) may resolve the light warning but low fluid usually portends something more serious such as a leak somewhere in a brake line, a leaking caliper or wheel cylinder, although it is possible to show a low fluid condition if disk pads or drum linings are worn so thin that a greater volume of fluid remains in the lines for effective brake function. Hopefully someone else can come up with the parking brake switch location for you.
  • Thanks for the good tip about the brake fluid level. I did not realize that there were sensors to warn of low brake fluid. I did top off my brake fluid, and will see what happens this morning on the way to work. I have a feeling, though, that this will not stop my brake light from coming on. I didn't mention it earlier, but from time to time, I have tried pulling up slightly on the parking brake lever, and then slamming it down quickly, and this has turned the brake light off. Even that hasn't been effective lately, though, which leads me more in the direction of a bad or mis-adjusted park brake switch.
    I guess I wouldn't mind the brake light being on, as I know that the car rolls freely, having pushed it with the brakes off. But each time the light goes on, it dis-engages my cruise control.... a big bummer when you're on the highway. Still looking for the location of the switch.
  • I just replaced my front brakes, the rotor and caliper on the drivers side 2 months ago. Drivers side brakes are sticking will not release correctly, already went through entire pad. Also right rear also seems to be sticking and not releasing, brake lines seem to be fine and I bleed brakes when installed. Can someone tell me what the problem is so I don't replace parts that are not needed.

    Thank You :mad:

    Your rubber brake line near the brakes has most likely colapsed inside the hose. When you press brake pedal the fluid will pass through the hose but won't release the pressure so the caliber sticks even after you release the pedal. If you've already went through a pad you've probably ruined your new rotor. You should replace rubber brake hoses if they look cracked and dried out
  • If only the pad opposite the caliper piston is worn, it means your pins are rusty and need to be replaced. It's not a good idea to work on your brakes unless you know exactly how they work, and what purpose each part has. The pins must allow the caliper to float so that the non-excited pad can move away from the rotor. If the caliper does not float, the inside pad will not release.

    :confuse: times are rough for me and im sure lots of you. i just need a SLIGHT push in a certain direction as far as my car being legal and fixed. heres the problems from most important to whatever:

    IDLE CONTROL - car revs up and down constantly when in park or neutral - was told by a couple people its the IAC controller? how much? whats the part exactly called so i can look it up?

    A/C PROBLEMS - A/C works fine when car is started then as i sit somewhere or at a light air gets humid and hot, and tempature gage goes up so i have to turn it off for a bit. only works perfect on highway or steady driving. ( i live in PHILLY :( )

    LIGHT PROBLEMS: front left headlight bulb is out. replaced the bulb, went out again, replaced socket and bulb, went out again. wires maybe? and my TAILLIGHTS go out once in a while ALWAYS ALONG WITH my interior dash lights and instrument panel lights. this happens once in a while, on and off. brakelights always work tho, also third brakelight is out but havent checked that bulb yet, could that be causing problems?

    and if anybody is NEAR philly, and would help me get my car back into shape, of course i would pay you, we could help each other, whatever im a chill dude looking to avoid getting ripped off by pep boys. THANKS for looking ANY help on ANY of the problems is appreciated. also email me at DJREKER215@GMAIL.COM

    1. Could be the IAC valve, but it may just need to be cleaned, not necessarily replaced. IAC = idle air control. Could also be the TPS (throttle position sensor) or the PCM (powertrain control module), but the IAC is the problem 90% of the time in my experience.
    2. When the A/C is on, are the cooling fans running full time? If not, then it will run hot at idle (or when no air is flowing over the radiator, like when stopped at a traffic light), and the A/C condensor won't get cooled. Most like the A/C system will shut down to protect itself under this condition. The A/C charge should also be checked.
    3. Could be lots of things. Coincidence maybe on the headlight, or corroded contacts, poor connections. Interior and tail lights, ditto, but may also be a worn ignition switch.
  • I'm a female drving a 2003 Pontiac GrandAM and am not sure I have been given good advice.

    My car WAS also idling high at a complete stop when in park. I had someone adjust the idle setting to low. Now it no longer idles high, but acceleration is jerky and very slow now, where before the idler adjustment, it accelerated just fine.

    Can some one explain where the idle adjustment switch is so I can try to reset the idle adjustment. When the guy adjusted lower it didn't seem to require a lot of tools or effort. So it seems a simple enough adjustment.

    My check engine light is also on now and a diagnostic indicated that my first o2 sensor in the bank 1 location is bad. I've been told that could be the cause of a high idle. I just want, in the meantime while I'm waiting on getting my o2 sensor, to be able to drive my vehicle the way it was driving before the idle adjustment. I feel as though I'm slowing all the traffice behind me. :(

    There's no "idle adjustment". The idle speed is set by the IAC on a modern fuel injected engine. The IAC is controlled by the PCM which gets input from other sensors as to what the needed idle speed is. The IAC controls the amount of air that is allowed to bypass the throttle body when the butterfly valve is completely closed, like when your foot is off the accelerator.
    I don't know what was done to it, but it doesn't sound like it was good.

    choleycole,
    burdawg is correct. The Powertrain Control Module constantly adjusts the Idle Air Control to maintain about 750 rpm when the Throttle Position Sensor indicates zero throttle. If, for instance, you shift from Drive to Park, the load on the engine will be less, and the engine will speed up. The Powertrain Control Module will see the increase in RPM, and then adjust the Idle Air Control to slow it back down. If your vehicle was idling at a higher RPM, it's very likely that the Idle Air Control Valve (a mechanical part) was sticking, and therefore not shutting down the idle air bypass enough to let the engine idle at the proper low speed. Whoever adjusted your idle may have somehow changed the point at which it sticks. It's also likely that when your engine is cold, it idles too slow, and when it warms up, it idles a little faster (If a sticky IAC is the problem). You could have a bad electrical connection between the Powertrain Control Module and the Idle Air Control.
    A competent mechanic should be able to hook a diagnostic scanner to your vehicle and determine exactly what is the problem. She will be able to see the signal for the Idle Air Control move up and down, and see that it is not causing any effect on the engine speed. Good Luck. Wish we could completely solve the problem for you, but this is something that needs hands-on diagnostics.

  • You are a perfect candidate for a Service Manual
    A service manual for your Pontiac will give you step by step diagnostics to solve your wiring problems. There really isn't any other way. This is another of those problems that needs to be diganosed in a "hands-on" fashion, but the service manual will give you a tremendous amount of help.
  • does anyone know if my 2002 pontiac grand am 2.2 litre engine with 99000 miles has a timing chain or belt because i cant find in the maintenance manual when to replace it.
    I read somewhere that if it breaks the engine will be ruined.Can anyone help?
  • hI.
    THIS ALL STARTED WITH A BLOWN BACKUP LIGHT. I REPLACED IT, STILL IT DOES NOT GO ON ( LEFT DRIVER SIDE REAR ). I FOUND CORROSION ON THE CIRCUIT PLATE INSIDE THE LIGHT ASSY ON THE CIRCUIT PLATE AND DECIDED TO REPLACE IT WITH A ARCH AUTO 30 DOLLAR AFTER MARKET ONE WHICH I WAS TOLD IS COMPLETELY COMPATIBLE BUT MY PROBLEM SHOWED UP3 DAYS LATER.. WHAT A MISTAKE. I PUT THE BULBS IN, BULB FOR BULB, NOT USING EXCESSIVE PRESSURE JUST SNAPPING THEM IN ). BEFORE I KNEW IT,MY BATTERY WAS DRAINING OUT OVERNIGHT, MY DRLS WERE NOT WORKING, THE SWITCH WAS NOT WORKING, THE LEFT UPPER BRAKE LITE WAS OUT TOO. OMG.

    I WAS LUCKY AND WENT TO A REPUTABLE ELECTRONICS AUTO TROUBLESHOOTER AND THEY FIXXED THE PLATE WHICH CAME FROM CHINA FOR 170 AND THEY COULD HAVE TAKEN ME TO THE RIVER. BOTTOM LINE, I PROBABLY SHOULD HAVE SPENT THE 90 BUCKS FOR A GM CIRCUIT PLATE. BE VERY CAREFUL WITH AFTER MARKET PARTS FOR THIS CAR. LESSON LEARNED

    I have replaced the front fog lights, but I now need to replace the rear fog lights. When I talk to the rep at the auto parts places, they say that they don't know if or where you would find the rear fog lights. The question.... Are the rear fog lights the same part as the front fog lights?

    Thanks,

    Ned
  • burdawgburdawg Posts: 1,524
    There's no "fog lights" in the rear. Are you referring to the back up lights?

    2003 Grand Am trouble. engine 3400 - ODBII errors - O2 Sensor1 bank 1 error, Cylinder 1 misfire detected. Engine runs rough, white smoke from exhaust, clear fluid under car with toxic burnt oil smell (same as exhaust smell). Coolant low but filled it. Engine service light on solid but goes off at highway speeds. Any ideas??
  • I have a problem with the door lock (on the drivers side only-interior) which prevents me from being able to lock the door without using the key or leaning over and locking from passenger side. I don't have a remote so I have to utilize the buttons to lock the doors. The button feels kind of loose and this has been a problem for a few weeks. Now I have just experienced the window (drivers side only) will not roll down - all others work. Anyone have any suggestions on what problem could be? Thanks for your help!
  • Do you have electric door locks and electric windows? If so, it sounds like you will need a new door switch assembly.
    If you have electric door locks, I guess you know that you can push the button before you close the door, and then you have about 15 seconds before the door actually locks.
  • I appreciate the info. Yes, I have electric locks and windows. The door lock switch has power to it - this is the switch that is loose like something might have broken underneath because it will work sometimes if you hit it just right. The window, which of course has a different switch, doesn't do anything - like there's no power to it at all. This switch is not loose - just suddently quit working but the other windows work fine. So would it be the replacement window regulator that I need? I appreciate the info!
  • My reset isnt working for the change engine oil light. Now all the lights come on interemittantly. Any suggestions?
  • This car has the 3.1 ltre v-6 and was running very good my wife left it Running and when came back to it it wouldnt start I checked fuel pump its getting fuel also checked for spark all plugs have spark but car wont fire up acts like wants to turn over but wont any ideas for me.?
    Thank You, Ramajama83
  • My 1999 grand prix just started to surge at all rpm's i changed the fuel filter any other idea's?
  • bob252bob252 Posts: 45
    You didn't say which engine, anyway use carb & fuel injection cleaner on the throttle body, (where the air filter is connected to the engine), also the idle air controller may need cleaning. My wife's car (3.1) occasionaly has this problem and that usualy fixes it. Check all of the vacuum lines as well,especialy where there is rubber to plastic connections. Hope this helps.
