Well Larry, you started that thread asking where all the a/c posts were..here's mine..



In my 91, my a/c was converted from R12 to R134a back in 2010 by the previous owner. The fittings where changed and a sticker was installed. Not sure what else was done but thats all that I can visibly see.

I had to add a can of R134a a few weeks back as it has evidently leaked out?

Since the recharge it has been doing well though, nice and cold, no complaints about that.

I do notice some odd sounds from the a/c compressor when its engaged. I've attached a video here for you to listen. When I put the climate control into EC mode the noise goes away so I figure its either a) from the a/c compressor or b) caused by the additional load of the a/c compressor...

My questions:

1) Is this indicative of compressor failure?

2) Low oil?

3) If 1 is true, would it be worth while to buy all the necessary components to make this a true 124, 134a system? If so, what would those components be? new condenser, compressor and o-rings?
