#6 of 21 a/c gounding circuit
May 20, 2008 (7:09 am)
I have a 1990 chevy lumina. The a/c was working fine but suddenly stop. I have check all switch on lines and compressor with volt and ohm meter. I have no ground for a/c relay to complete circuit. I have trace wiring to and from the computer connectors with ohm meter too.The coolant fan relay that is suppose to energize at the same time has no ground either. But if manually ground either one that circuits work .. any help?
#7 of 21 Insufficient heat
Jan 14, 2009 (6:43 am)
Hello. I have a `95 Lumina car with a 3.1, with 280 000KMs. Single zone heat and A/C. I bought it used last August. It`s used as a taxi. I`ve replaced 2 head and intake gaskets as well as a rad, heater core and pump and installed a used head! All new parts. I`ve also replaced the thermostat 3 times, 2 of the themostats are OEM. Most of this work was done before the cold weather. I just can`t get enough heat to the vents on any setting. I`ve checked the heater hoses for heat...both are hot. I`ve tried many times to get any remaining air out of the system. There is sometimes a gurgling in the heater core, but not always. I know...air. But, every couple of days I try to bleed any air out. None.
Could this simply be a switch problem?? I put about 400KMs per day on this car...there shouldn`t be anymore air. Anyone had a similar problem?

one of the fans should come on after idleing for about 5-10 minutes.
otherwise im sure you'd have overheating problems.

It appears that I have a worn out fan motor on the a/c blower.
The a/c fan won't blow cool air, or any air for that matter. But at times when I crank the car, you can hear the fan turn for a few seconds but it never reaches high rpm's and then it stops turning.
The auto parts store says the fan is $40.00. But I looked and cant see where the fan motor is located. I was told that its not hard to replace, or reach.
Has anyone replaced one of these, if so please tell me what I'm up against and where in heck is that fan motor located?

I have a 98 Lumina with the A/C problem of no air, cold or warm, when accelerating (most likely a vacuum leak) so I've been looking under the dashboard and I found where the blower motor is located. It's on the passenger side, under the glove compartment almost against the firewall. You have to remove the sound deadening material from directly below the glove compartment to see it. It's a dull metallic color, round on the bottom, about the size of a small coffee cup, with one electrical connector attached. It's an uncomfortable working area, your head will need to be where the passengers feet normally go. It's looks like only a couple of small screws hold it in place, but repairs like this tend to be extremely aggravating so have a couple of aspirin ready.

THANKS! Thats a huge help. I'm sure I can find it now, but I'm not the kind of guy that can easily fit in that spot. I'm 6' 4" and 250 so its going to be real fun, especially in the heat. Maybe I'll get a light and do it after dark. Thanks again.

You're welcome, I hope it fixed the problem. Speaking of which, this may be of help to others. My Lumina (98 with 3.8) would stop blowing air, hot or cold regardless of the ventilation switch setting or fan speed whenever the engine was under load (not w/o throttle,map sensor over 23). The fix, for my car anyway, was to replace the vacuum line to the vacuum reservoir. The line runs from a T connector near the positive terminal of the battery, under the windshield washer fluid tank into the driver side fender. It hooks to the vacuum reservoir, a black, hard plastic sphere about the size of a large grapefruit. You can access the reservoir by removing the battery or from underneath by removing the plastic panel directly below the driver's side side marker. Somehow the line had been crushed, most likely when I replaced the battery.
#14 of 21 2000 Lumina: Won't Idle...Just Dies
Sep 03, 2009 (11:57 pm)
Here's is what its doing: Lately, I've had to give it a little gas at startup to keep it from dropping down to a very low idle and then it dies. This happens in seconds and it does not stop at about 700 rpm where it would normally unless I give it that little bit of gas and let off the gas slowly. Then, the Lumina would sit at 700 and idle just fine.
Tonight, things got a little worse. Now, unless I keep giving it gas, it will drop right off and die. It will no longer fall down to 700 rpm and idle there as usual though I give it gas at the start.
So, as I drove home tonight, the engine ran fine, but as soon as I let off the gas, the car died on the spot. At lights, I had to depress the brake and gas at the same time to keep the car running.
Ideas please! What is it!?
(possible dirty air filter, way past needing new oil change, been too busy, and gas filter is a year old. New spark plugs about 8 months back. Spark plug wires OEM from day 1, got a CEL but no ideas yet as to what it is. Going to autozone to use their reader)
