How to troubleshoot my air conditioning?

There are many different ways to go about troubleshooting your car air conditioning system. The best approach is to determine if it is a mechanical failure or electrical failure. Then diagnose the the problem in that manner. For example: If the air conditioning compressor clutch is not engaging it could be caused by no freon, or low freon charge which would be a mechanical failure. Also it could be caused by an electrical problem and no power is getting to the compressor. In order to diagnose the problem follow these steps: Troubleshooting your Air Conditioning System Step by Step

started loosing overdrive, then drive and when we came to a stop

I just put a motor and automatic trans that has 46,000 miles on it in my sons 2003 kia rio. It runs good and was shifting fine but after a few miles we started loosing overdrive, then drive and when we came to a stop and took off again it wouldn't come out of 2nd. We had trouble with the plug on the newer trans that slips over the rod on top of the trans that connects to your shifter inside. It looks like some sort of sensor switch. It wouldn't stay connected when plugged into the wiring harness and kept the car from cranking and seemed to affect the shifting. We switched it with a used one and worked fine at first but then went back to the shifting problem. Does it sound like a tranny problem or is this piece we switched a sensor that affects when the gears change and needs to be replaced with a new one. The guy we got the motor and trans from is pretty trust worthy and will switch the trans out if its a problem.

Starter finally went out. Got the dreaded click when ignition key turned

I have a 1996 Chevy suburban. Starter finally went out. Got the dreaded click when ignition key turned. New starter put in with no problems. Connected the positive lead then when I went to connect the negative lead it sparks and you hear the starter try to engage. no key in the ignition switch. Stater checked out fine again after I took it back to have it checked. pulled the starter relay and it still did the same thing. any ideas?

Answer:

You've got wires crossed, on wrong posts, or touching. the main wire on the starter cannot touch the smaller wires on the solenoid.

where is the camshaft position sensor located on my gm engine? It's a 1997 3100 engine code P0341

where is the camshaft position sensor located on my gm engine? It's a 1997 3100 engine (6 cylinder) I ran a diagnostics and it came out code P0341 which is the camshaft position sensor. I was thinking of replacing the sensor and see if the problem goes away. The problem is that the engine looses power at higher RPMs. This code fault is the only one in the computer. I do not know the physical location of this sensor to replace it. Can you describe exactly where it is on my engine?
Answer:
It should be located right below the back of the power steering pump on the lower intake manifold.

I have a 1998 Mitsubishi Magna, Auto, which has just started to judder under acceleration. The engine rev's fine, but I set off, the car judders, and lacks power. The problem stops after 15minutes, once everything is warm. Any idea's what it is?

Answer:

There are three things I would like for you to inspect first off. Ensure that the timing is correct and has not jumped, this will cause the judder you mention if it has jumped. Inspect the fuel pressure at the fuel rail. If you have clogged fuel lines and/or fuel filter it will cause a lack of power, especially at start up. Also inspect the vacuum lines and ensure they are free of any cracks, damage or loose connections.

CV Half Shaft

Answer:

It will be a worn cv shaft joint. You can probably hear it under sharp turns.

the transfer case was hummimg and has gotten very loud

I own a 1996 6 cyl Jeep Grand Cherokee 4X4, it has just over 200 thousand miles on it, the transfer case was humming and has gotten very loud. How many different things can be wrong in a transfer case and should I just try to find an entire transfer case(used) to replace it or could it be something simple and cheap(LOL) that I could check first?

Answer:

A loud transfer case humm is in most cases is a bad bearing. First thing to do is a transfer case service drain the fluid and check color. Also check the magnet for bearing shavings.If this is a bad bearing the transfer case will need to be taken apart and reared.
