I just picked up a nice 87 300SDL with 129K from a family member.

A/C stopped blowing cold and dealer claimed freon leak at the compressor. So we was replaced it last week along with a few other tidbits to the tune of nearly 2K.

1 road trip, 350 miles and 2 days later A/C stops blowing cold again. I noticed under hood two caps, one blue and one red were left off just sitting on the frame.

I can see the valves left exposed to what look like part of the AC assembly so I'm wondering if those caps being off could be the cause?

Anyone know a quality benz service shop in the Dallas/Fort Worth area?
