Last week I posted a question about my cruisair that wasn't working and got lots of good info, so, here's a follow up.
Dropped the front bumper, which revealed all three units, as Jerry advertised. All were clearly marked as to which was which. Front, Mid, Rear. Easy enough. The front one swings out, giving access to all three units. But I have no idea how one would go about removing the rear unit from this really tight space. Obviously, the lines would have to be removed first. Can you just take the lines off, or do you have to suck the R-122 out of the units first? Then, does anybody know, once you take the lines off, will the unit just slide out, or is it bolted down somehow? I would think it would somehow be attached to the floor. Or, should I just leave it there and get somebody to vacuum test the unit and fill 'er up if need be?
Also, where is this much talked about sight glass? Do I have to take the top off the unit to see it? If so, do I really have to remove all of those hex-head screws to get the top off? There sure are a lot of them.
OK, now for the A/C neophyte questions. (Oh, you thought I already asked those?) Can I do a vacuum test myself? When you suck out the refrigerant, where do you put it? What sucks it out? Do you reuse it? Can you get R-122 from any old A/C outfit? Do they have to fill it up?
Any suggestions how I should go about fixing this rear unit? Could I take it out myself and tinker? Is this the kind of job that I should let the pros deal with? Can I remove the unit, throw it in my car and bring it to a shop? or do I have to bring the whole bus in? The more I type, the less qualified I feel to deal with this issue.
Thanks for any advice.
