97 chevy k2500 parking lites stay on,killing battire

must have a short somewhere , as a emergency fix and to stop your battery getting ruined take out the fuse that relates to the parking lights,then get an auto electrician to check out the problem as electrical problems can be a nightmare so go straight to a professional as will save you time and money in the long run

will this do? If not, please let me know what else you need.
turn signals/brakes are yellow, parking lights/marker lights/license plate light, are brown, ground is black. Backup lights are Lt green.

I think your trouble is in the turn signall switch, just had the same trouble on my truck. Turn signall switch is about $250 because it is actually turn signalls, wipers, washers, 4 ways, and dimmer all in one.

Sounds like you 've got a cross connection in the rear right taillight bulb, or wiring to that area.
Start by pulling the bulbs out and checking if it makes any difference with the bulb removed. Check the brake pedal...see if the parking lights still come on.
Look at the bulb socket contacts, and the bulb contacts and look for black marks, or burned out filament in the bulb.. if everything looks good there, start tracing the wiring back and look for cuts or a place where the wiring may have been pinched, cut, bared etc. if your right turn signal isn't working and the parking lites are getting triggered, it's got to be in that right rear taillight or wiring...

have your ABS system scaned for codes(intermtent code) as for the car not goin out of park when applying the brake,there is a level or linkage that works as a safety,this linkage may need adjustment.the linkeage goes from thr pedal(brake) to the shifter,some of the work thru a selenoid that gets activated when the switch is on.

Try this website :-http://www.compnine.com/index I used it to fit a parking brake to our 1999 sierra that had them missing

I would start by scanning the vehicle for codes, if none are present i would check for fuel and spark and then check timing belt. It could be a number of reasons, check the above out and we can go from there.

Oh boy, Chevy uses 3 important wires to make up their tail light harness. Brown is used for your parking lights and yellow and green are your signal and brake light wires, yellow one side, green the other. You have some seriously crossed wires. Start with tracing the lic plate lite since that works. Make sure it leads into your main parking lights and the ground wires from these tail lites aren't cut. The lic place lite will work with just power because the body of the lite is grounded with the bumper. Then make sure that there is power to the signal wires. You can do this with a test light and the signal light switched on. You don't need anyone to step on the brakes since it's the same signal, only interepted. Most importantly, Remove the tail lites and check grounds!! Good luck

If your idle is going from 500rpms to 1000rpm's fluctuating at and idle your EGR valve is probably carbon up and needs cleaned or replace.
