Air Conditioning

Ok, checked all 4, 50amp fuses. & 2 small fusrs for AC. All good. Started it this morning and 4x4 light off. I did the lock to lock last night. Also had a turn engin off! Oil press warning. Sut off restarted all good. No lights no codes with Mac et50 code reader. I am thinking this thing needs a new battery. Even though was @ 13.8 &13.8 at 2 clamps when in had Dis hooked up. I am also getting 0lbs press on high side and 0 lbs press on low with AC guages hooked up. I put in a can and 6 oz oil stop leak can. They emptyd awefully fast. I bet Oring gone some where. I just boughg this thing. 186k on it. Been ordering grometts and things and seals since last Sun. Hopefully some will get here soon. To access compressor, go from bottom & remove belly pan? Or take off air box intake? I can hook up INPA. I also have a whole bag of orings from rock auto that are AC spevific. Green . I dont remember compsition of orings.

Ok inalso have a HF vaccume pump and a kitbto intorudce UV dye in the system. & a UV light. Just wanting to know a start point. The guy i got this x5 from gets bent over all the time. More money than brains type of guy. So i would not doubt some one loosesend the lines up somewhere. I think i will go after door latch right now.

Main fan in front of motor never runs. Dis GT1 says tecirculation fault 640002. Inpa says voltage ok Dis say low voltage connect battery charger. Inpa 13.8v.

i push schrader valve by radiator support, no pressure. isn t this the high side? i put some UV dye in little transfer canister to introduce into ac system. no leaks but seems high preasure. i put gauges on and no pressure on either high or low side. hmmm . the gauges work. almost new. i have used them before. i can depress shrader valve by firewall. no preasure there either. GT 1 says recirculation malfumction 640002. i was mistaken on main cooling fan running. it is not. is there a way to jumper the sensor? i ran short test in INPA and gt1 55. any thoughts from amy memebers? wow cooling fan assembly. $524 . any good sources for this?

If you're depressing the shrader and nothing comes out, you have no pressure in the system....you have a leak somewhere

Ok, unplugged pressure switch under airbox. Fan takes off like a 747. Getting cooler air from vents. But not cold. Could be ambient cooler temps outside. So.... compessor? Or ..... what is longest life out of a compressor clutch for AC. Guy i bought from purchased with 75000 on it. CPO. SEEMS TO HAhave been well maintained except last oil change is overdue & sunroof drains plugged.

With 187k on it i am thinking compressor bearings out and 134a leaks out. Seems like the most logical.

With that kind of mileage on it, anything is possible. Could be o-rings that are no longer sealing, could be a puncture in the condenser coil from road debris hitting it, could be one of the shraeder valves is no longer holding pressure. Find the leak and go from there. Throwing parts at an AC system gets to be pretty expensive if you don't have a recovery machine to recover the refrigerant after you refill it, not to mention what you are doing to the atmosphere by leaking or releasing refrigerant into the air.
