Dash a/c problem
2008 Berkshire 350bh
My dash air has never gotten very cold, so today I put a gauge on it.
On the low side, it was measuring just under 30psi...the lowest part of the "full" side. So, I decided to bring that up a bit.
I added 12oz of 134a, and it barely moved up above 30. So I added a second can of 12oz. Then the gauge started going up to 75psi...well into the red.
Now it cycles back down to about 40-45, then quickly increases up to 70-75. Stays there for a 10-20 seconds, then back down to 45 for 1-2 seconds.
And to top that off, the air doesn't feel any colder coming out of the dash.
I tried bleeding off some through the low side a couple times, but that didn't seem to make a difference. The 4th (and last time), some yellow oil came out. So I stopped that!
Any ideas what I need to do from here?
And in the big picture, does your dash air get very cold?
