well the first day over 90* hit today and it was miserable driving my dschwarz m3 without any a/c.
2 months ago my friend and I fixed my a/c. the clutch wasn't engaging until we found that the overtemp switch had failed open. with that jumped we pulled a vacuum and recharged w/ r12. this was using a real a/c machine btw. it blew cold and i was happy. haven't turned it on since.
so on sunday i tried running my a/c and noticed the clutch wasn't engaging anymore. i checked all the wiring, but it was fine. the clutch engages if i jump the low pressure switch so i'm thinking i have a leak somewhere. i haven't taken it back to my friend yet, but i'm guessing i have a leaking hose or o-rings. has anyone ever replaced the hoses or o-rings? i found the hoses in the ETK, but the o-ring locations are not specified just their sizes.
and assuming i fix up the leak, should i replace the drier/reciever or would pulling a vacuum for 60mins prior to recharging get all the moisture out? i've seen some mention that the new drier eliminates the low pressure switch, which seems odd. isn't it bad to run the compressor w/o refrigerant?
