Hmmm... that's a darned good question! I'm guessing that you mean this happens when the car is started, as opposed to turning the key to "on" without starting it? Does it happen every time? I can't remember if the '99 still has daytime running lights or not, but if so, do they work properly? Do the headlights work properly IE; high and low beams all work? Maybe with a little more info, we can be of more help. FriPilot There are a couple [guessingly] related issues. Firstly, when I start the car, put it in gear (usually reverse), and then take off the e-brake, my driver side headlight blinks (preety sure it's the high beam). It clicks on and off repeatedly for about 4 seconds, and then stops (doesn't do it if I turn the headlights on right away). Also, after the car has been started, my DRL dash light blinks, and that happens 24/7, unless the headlights are on. I have tried replacing the DRL relay, as well as the bulbs. (2 consecutive bulbs burned out in the driver side lamp, not sure if I had all the blinking problems happened before that). Phil. =Hmm...= That's still pretty strange, Phil. About the blinking headlight, does it do that when you shift from park to reverse regardless of whether or not the parking brake is set or released? Or does it only blink when you go through the combination of shifting to reverse AND releasing the brake? I ask this because it might help to localize the problem. Either or both of those two actions cause indicator lights to operate, right? The gear selector light or indicator changes from Park to Reverse, and I imagine there is a light telling you that the parking brake is on. I'm beginning to wonder if one or both of those lights are shorted or connected somehow to the headlight circuit. That might also explain why the DRL bulbs keep blowing. FriPilot ==More additional info== It does it when the brake is off and it's put into gear. I can skip the brake, put it into gear, and then take off the brake and it'll trip the light. or I can release the brake, and then put it in reverse, and then the light'll go. I've looked over the wiring diagram, and I don't think the circuit crosses with the brake at all. ....?
beside the drivers seat...on the floor
the rad drain plug is located on the drivers side behind the front bumper
under dash drivers side mounted above the brake pedal
No, you do not have to remove the battery. Just remove the 2 bolts (1/2 socket) on the top and pull out the whole assembly. Then undo the big plastic nut and remove bulb and redo steps to install.
You can GOOGLE Pontiac Door Lock and find a lot of hits. Try this one; http://www2.partstrain.com/store/ FriPilot
sitting in car drivers seat it is located above left foot on firewall
it's located in the engine compartment, beside the air cleaner,on the drivers side.
if you have a 2.2,its mounted in the plastic intake manifold,and has a flex pipe that connects to the back side of the head on the drivers side
I suspect its because of a defective door jamb switch, which is inside the drivers door on the engine side.
unplug the alarm fuse 10 in the fuse box located when you open the drivers side door. it will trip the theft system momentarily, possibly starting. also you may have wiring problems if it starts and stop. passlock sensor, ignition switch, etc
the fuse for the rear defogger is in the fuse pannel located next to the drivers door. on a 2001 sunfire it will be a 30 amp fuse located on the bottom row third fuse towards the door
On our 2000 Sunfire, it is the black plastic relay inside the fuse box on the side of the dashboard, drivers side, upper right corner. The fuse box cover shows which object it is. (different user) On my 96 Sunfire it is behind the bumper on the left side (driver's side headlight housing must be removed) It is a little larger than a standard 12 volt relay (approx 1.5" x 1.5" x 2.5" when plugged in, almost a cube when not (no connector)
