4 half inch u bolts on the rear of the drive shaft and out it comes easy job 2 of the caps are easily removed the other two are drove into the drive line.. you might need a press or a hammer and a 3/4 socket to get them out.

Get a 'kit' from any local automotive 'box store' and it will have the proper connector for the low-side refrigerant line and will be full of R134 refrigerant. Since the truck is a bit older, I would use a refrigerant with compressor oil mixed into the 'freon'.

Check Freon levels, have a shop vacuum out old and replace with new with lubricant. less than $150, worth doing anyway.

There are several steps to removing the oil pan, especially if your 1500 is a 4 wheel drive. It's a pretty involved procedure. You are way better off buying a repair manual, such as the Haynes manual for your vehicle.

The only way that could be possible is if a/c is some how switching the fan off at the radiator/condenser, so first question is with the engine running and a/c off see if the cooling fan kicks in, if it does and at the exact same time when it does, switch the a/c on and see if the fans turn off! The fans should be on or switching on and off when air con is on, hope this puts you in the right direction

Vent ducts are controlled by vacuum valves, listen for suction sounds from the dashboard while moving though zone selections. If heard replace bad hose or repair the current hose.

cranks but wont fire or wont crank? tries to start or doesent even try to fire?. Jon.

Check that your spark plugs wires are properly connected. Check your spark plugs and see if they look good. Check your gas input and gas filter. Take your gas hose off at the fuel injection port and see if gas is coming out of the hose. If not, it could be your gas filter.

check and see if its getting fire if it is check and see if it is getting fuel

I had a similar issue on an 05 silverado. Air would only blow out of defrost vents. But this worked for me: 1) Unplug HVAC fuse for 10-30 seconds 2) Start truck 3) A/C comes out defrost - wait about 10 to 15 secs 4) A/C then starts coming out the floor vents for about 5 seconds 5) A/C then starts coming out the dash vents. 6) While the A/C is coming out the dash vents, turn A/C OFF (otherwise it cycles back to defrost for good). 7) Turn truck OFF 8) Restart truck and it should work fine (Found solution on another forum from user "ccurran")

What do you need to know exactly?

bad how? remove switch, cycle it with key and listen, hear clicks ? if not, lubricate, graphite best, tumblers should move freely and pins snap into place
