New Problem With My "New" Tractor.

I doubt the ac is overcharged, this is a recent development correct? Untill the puddle in the floor, the ac worked fine, right? Even if it was overcharged, which is not likely, when you turn on the ac the compressor does not run all the time. It has sensors, high and low pressure. If the high side gets to high it cuts the compressor off. The pressure drops and the ac cycles back on, and the cycle continues. Check the drain line, regaurdless of the amount of freon in the system the drain should not allow water into the cab.

 

The drain tube may be coming out of the front of the firewall, and not be very long in length, and it should be made of rubber. Look LOW on the fire wall, it will not be on top, heck, it may not even be mid way, usually LOW. Look around the heater box, then follow down from there. it may be hidden by wires, and air lines. You may not find it easily from looking under the hood, but rather you may need to get under the truck.


If not in the area of the firewall, then it very well may be under the cab towards the front, on the passenger side. again, it may be stubby, not very long.

If you do not get to drain out the system, you will end up with mold and a whole new set of issues, including of course inhaling that stuff, along with a nasty odor.

 

Have you checked the bolts on your drive shaft at the connections with the center bearing and transmission. Somebody may have done work to it and was a dummy and didn't tighten things up

 

I just remembered one time when my transmission was shaking some I discovered that I had a broken transmission mount.
So that sucked.....

 

2.5 years no A/C 100+ every summer inside the cab. you get used to it, although I will say this summer I would like to fix the A/C if I can ever manage to get ahead. Sorry for the misfortune believe me I feel your pain with no A/C. But I don't feel your pain on the truck mine has it's quorks but she's got a lot more miles on her.

 

It's a tough racket.
Lease purchase is even tougher.
Take the long view.
I just went through 6 weeks of breakdowns and crappy loads.
But I still paid my mortgage and made my payments.

 

Make sure you are running your AC on Recirculate.

You may have a clogged drain on the AC drip pan. You should be able to see where it drains by opening the hood and look under the cab on the passenger side, an air hose or water hose shot into the drain momentarily will usually clear it. If the AC is constantly freezing up it may be low on Freon, a low charge of Freon will actually produce freezing temps. You could also get a temp probe to put in your vents to check the temp coming out of the vents. If it is near freezing you are probably low on refrigerant.

If none of these conditions are apparent you are probably getting ready to lose your compressor, and the intermittent loss of cooling could be because the expansion valve is getting clogged with fine metal coming from the compressor.

If you know of a good reasonable AC shop it may pay to get the system checked, before you find yourself in dire straits. ( Death Valley and no AC) You might get by with a cleaning of your refrigerant and some oil, if your compressor is in reasonably decent shape. A decnt tech will be able to tell you pretty quickly if the compressor is on its way out. If it is the original compressor and you have 200K on the truck you are probably due for a new one.
