well i thought i did this right my question is in the thread but here it is again ive a 1986 xjs v12 i have 30 oz of freon in and 3 oz of oil not leaking and can see freon moving in site glass and compessor is running and only heat is coming out and the garage put in a new sevo just before winter then the heat worked but i didnt check a/c untill now and i drained system and filled how i told you what could be wrong with ac

 

First of all, welcome.

The word "servo" has me stumped a tad, as the '86 is known as the Delonair 2 system, which is primarily vacuam operated.

Maybe the heater tap is jammed OPEN, very common.

As for the Freon, NO idea. All a/c work down here is regulated and a license is required to work on the system.

From the OLD OLD days of R12, any bubbles in the sight glass meant the system was "under charged", but gauges on the HI and LO side are really needed to get it right. Also we used to vac the system down prior to recharging.

Someone in your market will cruise by soon and answer.

I also suggest that "questions" are posted in the related forum section, XJ-S in this case, that way many more people see it, as not everyone comes in here that often.
