#593 of 745 2000 Chevy Tahoe won't start! by krmcpherson

Jan 03, 2010 (1:00 pm)

I have a 2000 chevy tahoe, that i've had for 2 years, it has a little over 15000 miles on it and we've never had any problems except for the battery dying, when we were a ways from home, the car started acting like it was outta gas, and after we pulled over we couldn't get it to stay running. dropped the tank and cleaned it out(had alot of sediment) replaced the fuel filter twice,(both of which needed cleaned after we tried to start) changed the fuel pump relay.The fuel pump itself will prime when the key is turned but it will never stay running, keeps trying but won't stay running more then a minute, and then our battery is usually dead and needs re charged.

Where do you live?
First off, I've changed 2 alternators in the past 3 years in my '96... might be the cause of the dead battery. Otherwise, check for a light staying on, ie glove-box, under the hood...?
You don't say if you changed the fuel pump, (low pressure) but I'd be looking for a gas line leak, sucking air, somewhere. Try bleeding the gas line at the engine, there should be what looks like a tire valve, if not, loosen the line...might be an air bubble, or dirt, jammed up in there...
If you're where the temperature goes between freezing and not, and do a few miles before it acts up, look for a vacuum leak to the breather... the breather warm-air valve, from the exhaust manifold don't work, causing intake gas to freeze, reducing gas flow. Usually, the valve is ok, it's the supply line that's leaking... find a full-time vacuum line and plug it there, to get home, or use a lot of gas-line ante-freeze!
Keep us posted!

Need to check fuel pressure to verify if the pump is good or not.

#596 of 745 96 Tahoe LT a/c won't work,.. by Robere

Feb 07, 2010 (5:57 am)

My a/c blower works fine,..( aside from some blower noise ) but there is no cold air. I have tried to recharge and it doesn't seem to take. A dealer has done a leak check and couldn't find any leaks. Occasionally, I hear a "gurgle" noise after the truck is turned off,...any suggestions? Could this problem be caused by a plugged drain line? Any help would be appreciated!

Did you (or the dealer) put on a set of pressure gauges, to measure the pressures in the system on the high and low side? This checks whether the compressor is able to pull down a vacuum to the correct low pressure, whether you have too little or too much freon in the system, whether you are getting freon flow thru the orifice, whether your high/low switches are working correctly, etc.
 
Once that is all working correctly, then they should check that air mixture doors are working correctly.

well only on the charge side,...the pressure when charging is good,..when the compressor kicks in the pressure drops and nothing is discharged from the charging canister,.............

#599 of 745 Missing wires on the new turn signal switch by oldtahoejim

Feb 08, 2010 (10:16 am)

I am trying to replace the turn signal switch on my 2000 Tahoe and the new part is missing a pair of wires with a quick connect that would connect to a switch directly behind the gear shift arm and this has something to do with taking the car out of Park. What does that control that is activated or de activated by the gear lever do? I'm guessing that it has something to do with the daytime running lights, but that is only a guess. By the way, the problem with the turn signal is that it continues to make the clicking noise after the wheel is centered. the lights are not flashing, but the noise is very annoying.

The charging bottle should be connected to the low side. With the compressor running, the low side should be ~30 psi and high side ~250 psi. These are very approx. numbers. When you open the valve to allow the freon into the low side, the pressure will go up because the freon vapor pressure is ~120 psi. Also the high pressure will start to go up. When the valve is closed, the low pressure should go back down. Be sure you don't over-charge.
 
Not sure I understand this: "and nothing is discharged from the charging canister,............. " Unless you have the bottle connected to the high side which is dangerous.

Thanks,..yes I did have the initial pressure but when the compressor kicked in,..pressure was lost,....I would think that would indicate a small leak? Bad compressor? However the dealer couldn't find any leaks,...
 
re: "nothing is dis,...." it seems no refridgerant left the container. The nipple on the charging unit doesnt fit on the high side,...so it was the low side,....

I find this hard to believe, you need to get a different 'dealer'. Is this a Chevrolet dealership you are taking it to? Any competent dealership should be able to find and fix air conditioning system problems. They can tear it apart and rebuild it, if they have to.
 
If this really was a Chev dealership, then go find another Chev dealership or a specialty air conditioning repair shop.
