Pretty simple, open the hood, on the back of the headlights, there are 2 flat plastic tabs about 5" long that pop up and out. These will release the whole assembly for removal.

I doubt you can actually fix it "yourself", but you can save lots of money by taking it to a radiator shop instead of buying a used or new radiator. They can replace the plastic tank for the bad side, but it is usually the drivers side because this is where the hottest water exits the engine and causes the plastic to crack. I removed the radiator myself and took mine to a shop and they repaired it for $40........cannot repair yourself because the tank has to be crimped on!!!! And radiator "stop leak" products will not work because they are for metal tanks!!!

check fuses under hood for the main power coming from battery

Under the hood near the battery.

Replace the turn signal switch. All the exterior lights run threw it except the high brake light. There is a small plastic clip/switch in it that controls high and low setting. Because of heat it starts to melt and quits working.

Check the cigar fuse located in the fuse block in the drivers side fuse block ( on the end of the dash). Let me know if you have any questions and I'll do my best to answer them.

02 sensor circuit low voltage ---answer is copied from obd-codes .com you can visit this site for more information if necessary Usually rear o2 sensor problems won't cause drivability issues since they are an input that measures catalyst efficiency (unlike front o2 sensors). However if you have other codes present, like lean codes or pre-o2 sensor codes, then they may cause drivability problems as well as P0143. The following symptoms may be present: MIL (Malfunction Indicator Lamp) illumination Engine performance issues Engine running rough Engine running rich (only if PCM is trying to add fuel to compensate for low o2 sensor voltage reading) Engine running lean (only if vacuum leak is large enough that PCM can't compensate by adding fuel) Poor idle Causes If you have reason to believe that your engine is running lean, fix that problem first, then clear codes and see if the P0157 code resets. An engine that is running lean could set this code, but usually there will be lean codes (P0171, P0174) present. The following could be causes: Air leaks in exhaust in front of o2 sensor giving false reading Engine running excessively lean O2 sensor connector damaged/corroded O2 sensor signal circuit is shorted to ground O2 sensor ground circuit is open O2 sensor has failed (it may be contaminated with fuel or coolant) PCM has failed Read more at: http://www.obd-codes.com/p0157 Copyright © OBD-Codes.com

There is a low pressure switch on the accumulator that if you jump the 2 contacts together it will energize the clutch, as long as everything else in the system is good.

My experience with that is a blown head gasket. Or the head is warped. Either will allow water to reach the oil pan.

check the engine control module in the dist and the pickup coil under it is control module is not bad. You can take the control module out and take it to most automotive parts shop and they can check them for free most of the time.

I know this is not what you want to hear but if you don't pay the bill on star will disable it for you or else you might pull the fuse out for it.

It may be in the fuse panel under the hood. If it is ok, check the cruise control kick out switch operated by the brake pedal. If mis adjusted or knocked out of position cruise will not work.

Sounds like dirty corroded battery post connections...remove from battery clean and/or replace the post push in terminals...these can be purchased through your local parts store for under $5. They are push out...push new in also clean inside the battery connections...be sure new posts are tight...all systems will need to reset after the dis-connect...Hope this helps.

no you could try to hit the tank with your hand hard it my start but not for long

Your normal braking will work fine even if the ABS control module is defective. You will however have no functioning ABS in an emergency when it is needed. You can continue to drive it without ABS but if you want the ABS to work you will have to have it repaired.

If EGR comes up, take it off and clean it, see if that clears it up, it may be sticking. Would also clean your throttle body, and replace fuel filter.

Column shift cars it will be at base on steering column I think. Floor shift cars it may be inside console at shifter. At some point this switch started being mounted on the driver's side of the transmission but not sure what year.

The computer should be located under the hood. It's silver and has two large connectors with about 160 wires distributed between the two. GM usually parks that computer by the battery on top of a fender well.

I agree with the first two answers. If that does not help, get a multi meter and run continuity checks on the wire harness.
