First off, yes, I know I should replace the dryer. So in the question below I know the answer is "replace the dryer" but also answering the question I'm actually asking will be much more helpful.
When I got my TJ the A/C Schrader valves were bad so the system was down/out on refrigerant. I replaced them and now it will hold vacuum without dropping over the course of a week or so.
My two questions then are;
1) Using the AutoZone rental manifold gauges and vacuum pump I can pull about 26" Hg and that's where it sticks. But it should pull 29 right? So is the 26 because of bad free loaner tools, a system fault, a bad part? Again, after I disconnect the vac pump and gauges the system will hold at the 25-26" range so it's not dropping like it has a leak.
2) Consider me a cynic, but before I spend the money to replace the dryer I'd like to run some UV dye through the system with new refrigerant to verify if, in fact, the system does maybe have a miniscule leak anywhere. What will be the impact on the system if I go ahead and send it with the existing dryer? Air won't be as cold? The streams will cross and my Jeep will implode?
Thanks for any input!
