Find the air compressor located on the engine and follow the two metal tubes coming out of it. One tube is the high side and the other is the low side. Keep following them until you find a tee with a plastic cap. The red cap is the high side, the blue cap is the low side. If you're trying to re-charge the AC then the recharge fitting will only go on the low side, it won't fit the high side on purpose.

Where is the ac low pressure valve in a 2002 chevy mailbu

2002 Malibu is near the firewall on the passenger's side about a foot down. Really odd place and not that easy to reach. Obviously the design is not for DIYs. I have a Honda Accord and the high and low are side by side and very easy to service! Go Government Motors, well I guess it was the "old" GM them.

Oil guage fluctuates at low rpm-2002 chev. silverado. Repair program says unit is on oil pan. Chevy says its on top of motor behind intake manifold.

I believe the sensor in the pan is for the low oil level sensor. The oil pressure sensor is at the back of the engine, by the intake manifold, towards the passenger side.

2002 Chevy tahoe won't start turns over but won't start

Most common problem is low or no fuel pressure. You will need to get a fuel pressure reading and post back.
If there is no or low fuel pressure then most likly the fuel pump is bad and needs to be replaced.

Where is the low pressure a/c valve on a 2002

Normally, the low side switch is mounted on the line coming out of the condenser leading to the evaporator. On your vehicle, I believe it would be close to the firewall inside the engine compartment on the passenger side. Hope that helps.

Look for the accumulator(silver can a/c lines go to) on the passenger side of engine area. The Low side charging port cap should be on the side of the accumulator.
