Aircon question

[BillC]

On the weekend I was in my mates ute when the aircon stopped working. Literally working one minute then stopped. If you turn it off for 5 minutes it works again ? I talked him into going to an aircon guy I know and he said it was the condensor. The radiator thing that sits behind the dash just after the fan. He said that it was blocked probably by the fluff from his sheepskin seat covers. He said that because the air was not flowing through the condensor freely it was freezing up and stopping the coolent gas from flowing through it (or something like that). This has happened to me in the past in my ED and I tried to get to it to clean it but gave it up as too difficult. My question is how do you get to this condensor that gets blocked so you can clean it ? Has anybody done it. The aircon guy wants $550 to replace the condensor..
