AC and check oil issue

[samtheman77]

ON my 93 JGC my tank is full with freon and when the system is on i can feel the lines are cold but the cool air does not reach its destination. Any ideas what should i check?

Also is there any way to reset the check oil that flashes on the computer dash by the shifter?
Thanks

I yanked the computer dash by the shifter. It was real annoying. I took the computer part out, tossed it, and replaced the face. I am going to install my toggles and my CB mount there. It also got rid of that annoying beeping.

I am not sure about the AC problem, I have the same problem.

The VIC (Vehicle Information Center), you can reset it by pressing and holding the SET and SELECT buttons at the same time, then go through the steps (language, mileage to next due date, etc)

Both A/C lines should not be same temp. 1 should be noticeably warmer than other, Check freon level (134a). Also Jeep had problem with 93 GC's evaporator's leaking and extended warranty to 100k.

If when the blower is on high and no air is coming from the vents check to see that the blend door (Jeep also had a problem with them) is opening by applying vacuum to the operating motor under the dash on the passenger side.
Do you get heat from the vents? If not the Evaporator Core's fins maybe clogged with debris preventing air from flowing across evaporator.

actually the warranty on the evaporator was extended to 7 years 70000 miles so hes way out by time if not by mileage.also depending on what lines he is talking about,they could be the same temp. a quick way to check if an ac system is charged is to feel the lines at the evap.if the system is fully charged they will both feel cold and by hand you wont be able to tell the difference.if the line coming out and going back to the compressor is warm,the system would probably be under charged.the entire low side of the system should feel cold with the compressor running.obviously the high side lines would be a different story.for what its worth,I agree that the blend door actuator is a very likely cause.but on this jeep it is electrical not vacuum operated.they get destroyed when the ac drain gets clogged and the condensed water that fills the case runs out through the actuator
