Hi,

We have been running our dash ac neary constantly for the last week or more. All was fine until this morning when the Cairo coming through the dash vents was no longer cold. At lunch I pulled out my simple one gauge connector hose. It showed about 15 psi on the low side with the compressor spinning. I thought it was just low so screwed on a can of duracool, screwed in the piercing unit and backed it back out to let the incepted duracool drizzle in, or so I thought. The pressure showed about 30 psi when I was through but seemed to move around a bit. I remember the correct pressure being more like 20 to 25 psi but decided to try this somewhat higher pressure. No cool air at the registers. The day was not too hot, so we turned off the dash air. When we parked tonight I checked to make sure the compressor clutch is working correctly, cycling onn or off as the dash lever is moved from ac to vent.

Still no cold air at the dash vents. I remounted the gauge and it seems to fluctuate from around 30 to around 50. I tried bleeding off some pressure but the apparent pressure did not drop appreciably. I have only one more can of duracool with me and we are still a long way from home so I don't want to squander that last can.

Any ideas what I should look for or do now? Thanks, I really don't want to roast the rest of the way home.

Btw, we came into the Black Hills area in SD only to learn that this is the last weekend of the Sturgess Bile Week. How about 750,000 bikers all trying to get home starting tomorrow (Sat). Every road we have been on today has been bikers going both directions......Wall Drug was.....interesting with many different languages heard on the side walks. Fun times, but would be even more fun if I can fix the ac before Sharon has a cow.
