I have a 2001 ford ranger v6 4.0sohc the air conditioning goes in and out. still blows cold and only goes on when I fidget with the relay switch. has a brand new switch but still does it any solutions?
I don't know what relay switch you are speaking of, but the is a low pressure cutout switch on the receiver/dryer. (Small black tank in passenger rear of engine compartment). It cycles the compressor on and off with changes in the low pressure side of the system. If you have to move anything to get it working, chances are you have a bad wire or connecter going to the switch. Look for looseness in the wire or burned spots near the contacts. Again, I am not sure of the switch you are talking about. What is it's location?

sounds like a damper door in the front not working properly, these are actuated by the front temp control, the door is operated by either a manual cable, and electric actuator, or vacuum. I hope this helps you zero in on your problem. Merry Christmas
You will need R134a, and a filler hose. Charge the system on the low pressure side, it should have a blue cap on the charge point.
Your filler hose will only fit the low pressure side, just in case the cap has been removed.

Hello;
The Ford motors are pretty good. I had 280K on a 2.9 V-8 that only needed the oil changed every 3K. Unless you have fluctuatuation in the timing then you should be ok.
These engines use a chain rather than a belt and have excellent life.
Thanks;
