Last week a buddy brought his 60 to my house complaing of poor A/C performance. I told him what I did to mine, and how I fixed my A/C. His was exactly the same as mine.
When I bought my 60 the A/C did not work. I went to my A/C shop and had it converted to a full 134 system. It was very cold after, but no/low flow out the vents. A/C shop said it was a duct issue.
I went home to investigate. Started looking around and removing ducts and clips under the dash. After some time with flashlights and a mirror I found the problem.
The cooling coil (evaporator) was completely clogged with lint! I could grab hand fulls (actually finger fulls!) of lint. This blocked 90%+ of the airflow.
Getting inside the box around the coil is a nightmare. I ended up removing the carpet and front seat for room. I then made a special bent air nozzle with a rubber tip and started blowing. I aimed my shop vac to draw in a much debris as possible.
After getting a lot of lint and dust, I could still see many rows were still blocked. Next I used water and small home made nozzle. I also used a little dish soap. Wow... what a dfference. Crud flowed out everywhere. I also found some other areas where the vents where full of debris in the engine compartment and fender wells. I bet this junk helps to cause all Cruisers enemy... rust!
After a lot of time and vac work, I placed a big fan in the cab. The next day i put it all back together and gave her a try.
Well, it works better than I could of dreamed. I now have a meat locker on the hottest day. If you are having A/C issues, and everything appears to be working like it should, try this fix.
Our Cruisers are all 20+ years old and stuff collects in bad places. In this case the blower draws in junk and pushes it right into the coil, blocking the flow.
Check yours out.
