On vans with rear AC, the AC may stop blowing cold air due to a damaged AC line near the back of the engine. It is common for these lines to rub on the engine block, causing a hole in the line and a refrigerant leak.

    Ac has lost it's charge. I refilled the freon and the ac started to cool again. The compressor stopped clicking on and off. Well a day later the compressor started clicking again. Now I guess I'll be looking for a leak. Also the rear ac is still not working. I was hoping it was just because of the low freon. It has to have a leak for it to be low on freon anyway.

    AC quit working. Fans work great, but no cold air for AC in the summer
    Heather rear and front work fine.

  • Found that the hard aluminum line wore thru at a mounting bracket on the frame. Had to replace the entire line. Not a cheap fix.

    Took it in for estimate as air was not working in front or back. We had to pay 80 bucks to find out it won't hold Freon due to a leak and it has both front and rear ac, so to fix that is 1300 or so, or cut and cap it off and just run front ac for 600, I am putting up without are but may have to get if fixed after the oil leak.

    a/c no longer accepts Freon. due to leaking rear a/c

    the previous owner fixed the same issue. Mechanic take a huge precausion so this time hose rubed to exhaust manifold rather than engine body. I'm going to fix it.
