Re: Chev Express van rear AC failure

|I have a 2000 Express van, and the two lines that run to the rear AC coil |have failed. Apparently, the lines corroded where they are clipped to the |frame at some point. Is this common? | |My normal garage doing the work is willing to try to replace the lines, but |because of how they are routed they think it's going to be a very hard job. |The dealer says at least $1000 CDN, and won't do flat rate because of how |hard the job is, and how the fittings tend to corrode onto the coil and |strip off, etc. Basically, they don't know how far into the system they |will have to go until they start trying to take it apart. How hard is it to |change these lines anyway? | |I've asked the garage to block off or bypass the lines to the rear AC so |that the front AC will work, and they say they can do that. What I think is |that I really need the AC to be working at the front at least for the |defroster to work, and I don't know what damage may be caused by having the |system empty of refrigerant. Any ideas? Isn't there lubricant in the |refrigerant mix? | |This totally irritates me because I didn't order rear AC on the van in the |first place, it just showed up with it...

Yes, you can block off the rear and just run the front. YEs, there is oil in the system. A ncompetent tech should know whether any of it needs to be replaced. Have you considered replacing the metal with rubber hose and routing it under the vehicle and back in through new holes? You can use a compression fitting to join rubber to metal at each end.
