I found the problem!! FINALLY..... it was a corroded wire, covered by the sheathing................of course the power wire was fine..... it was the signal wire.............

Does anyone have a schematic of the 2000 Bonneville AC circuit? This is driving me crazy.... Direct current works the compressor, I have power to the plug, I've checked the fuse and relay, a computer diagnostic is calling for the AC compressor to be enabled, a new pressure switch did not work ...

Tried a new pressure switch and no luck. I have no codes in regard to it either. I also forgot to mention that I did put a scanner an it and it's "calling" for AC to come on, but the compressor is not activating..... I also have power at the plug, tested it with a volt meter..... I'm just assuming I ...

Tried that...but still can't get compressor to cut on.. I don't know if Compressor is bad, the pressure switch is bad, or the head unit is bad.....

Working on a 2000 Bonneville today. AC Compressor not working. Checked fuse and Relay and found both to be fine. Used external power source and compressor kicked in and ran. Checked for power at the plug with volt meter and had proper voltage there when ac was turned on at dash. The static pressure ...

We purchased a 2000 Impala LS (3800) and there was not a keyless remote from the seller.... So we got several remotes, and tried to synch them by using the prompts on the factory radio.....could not get the remotes to synch.....then used a GM Tech II tool and still could not get them to synch ...

Lights don't even come in when driver door is opened......they do when the other doors are opened.

Also, the radio stays on when the door is opened and does not turn off like normal??

This car is old, has 308,000 miles on it. The drivers door lock has stopped working, by key and/or remote.... I pulled the cover off and it appears the plastic mechanism that houses the remote has broken somehow and is loose....it further appears this looseness is causes kind of a blocking of the ...

I have changed the fluid, filter, and used Lucas Auto Tranny..... Car has 135k....... noise has been there since we owned the car about 18 months ago.

My daughter has an '00 Bonneville..... when the tranny shifts into Overdrive there is an irritating "whine" high pitched noise (only way I know to describe it) that starts..... when you shift it into 3rd or step on the gas to accelerate the noise goes away..... other than that it shifts smoothly and ...

I found the leak! It was leaking very slowly at the O-ring in the line set just before the compressor (The dye I put in confirmed where my Sniffer was hitting on)...... Changed out the O-ring, not leaking now...... Evacuating system and will recharge within the hour.

I will check it tomorrow, after it's had a day and 1/2 to circulate the dye. Always something..... obviously it's a slow leak because it held vaccuum at -30 for nearly an hour before I recharged it.

It was blowing very cold after the recharge...then today it stopped blowing cold.... I put the guages on, and I had 30 on the low side and just under 150 on the high side..... I have a leak somewhere....... I ran the lines with my 'sniffer' and only found one area of 'suspicion' but I've known that ...

I did, a full evacuation 2 days ago, replaced the oriface tube and a recharge with 3 12 oz. cans of 134A.

The charge is fine, It's 40-45 on low side, and 200-225 on the high side with ambient temps of about 90 degrees.

The air from the vents is about 42-45 degrees on the passenger side, and about 55-58 degrees on the drivers side. I have checked the blend doors and they all work for the entire range of motion. What else can I check?

Well the problem is fixed...replaced the Fuel Pump and it runs beautifully..... so glad GM started making an access panel in the trunk so the tank doesn't have to be removed..... I did the job in under a 1/2 hour..... AND with a redone hold down ring....... beating the daylights out of the old ring ...

Well, even though I pressed the shader valve and fuel spirted out....... I just went out had my daughter turn the key as I laid in the trunk..... NO sound from the fuel pump......... Hmmm....may be the problem.

My daughter went to the store this afternoon in her Impala LS (3800) and when she went back our half hour later the car would not start...called me..... I pressed the shader valve on the fuel line and fuel streams out quickly...... then I put my spark tester on the #1 plug and it had spark ...
