Car Air Conditioning Maintenance Service - Chevy Venture

Car Air Conditioning Maintenance Service - February 11, 2005

The part that was ordered on Feb. 8, 2005 finally came in from the dealer (the low-side service port valve).  I arrived at the shop at around 8:30 AM and walked to a nearby restaurant to have breakfast while they let the thing cool down and start work (valve is very close to the exhaust manifold).

By the time I got back (about 40 minutes), they already had the valve replaced, the system recharged, and they were checking everything out.  A few minutes later, the van was idling out front of the shop and was  blowing cold air (about 40 degrees F) from the dash vents.  I drove off with a working car air conditioner again!

Total cost, including parts, R134, oil, dye, and labor - $128.

Later in the afternoon (about 2:30PM), I went to pick up my son from school and noticed that the air coming out was not as cold as it was before.  We had a couple of errands to run, and at about 4PM noticed that the air coming out of the vents was NOT cold at all AND that the compressor was NOT coming on.

I went back to the shop and the guy that had done the work looked at it again and said that it was "his problem" (he implied that he should have fixed it right the first time).  He said that there was a leak at the same spot as before (see pictures above - dye is visible on the service port cap).  He suspects that at some time in the past, there was damage done where the valve seats in the service port.  He also said that he could not get a valve that has a larger seal at the base.  He was concerned that replacing the entire hose might be VERY expensive since the part had to be ordered from the dealer. 

Since it was late in the day on Friday, and I had to go out of town the following week, he said he would investigate what could be done besides replacing the entire hose.

UPDATE - Feb. 18, 2005
I called after returning from my business trip to see what could be done next.  His "expert" had been sick all week and had not been able to offer any advice.  I asked if he had priced the hose and he said "no".  I decided to give a couple of dealers a call and found that the hose was about $64. 

I took a trip to the dealer parts department to verify that it was the correct hose and discovered that the correct one was $55 and would have to be ordered (NOT in stock).  I faxed the parts diagram to the repair shop and gave them a call and he said that I should also order the seals on each end of the hose (the old ones cannot be reused) and he will install them. 

I ordered the parts ($93) and will be notified when they arrive. See Next AC Service Event
