2004 TB A/C Pressures

[price111]

I checked the AC pressures on my 2004 TB as the air does not seem as cold anymore. Pressures @ 80 degress ambient were 150 psi on the high side and 33 on the low side. Seems low to me but the dealer, after confirming pressures, said it's OK. I think that's bull. However, does anymore know the specific a/c pressures for this car?? The dealer also confirmed that the factory puts UV dye in the system (which I noticed after removing the gagues) and I'm going to check for leaks one of these evenings with the UV/yellow goggle routine. Temperature at vents is about 50 - the dealer said 39 but I totally disagree with that.

Thanks for any assistance here. Less than 3,000 miles left on warranty.

150psig hi side does seem low, but I don't know the specs for this system.

Well, it turns out that the factory puts UV dye in the refrigerant. Last night I checked with a UV light and my funky yellow goggles and, behold, there are two leaks where the flourescence shows up. The first is the line from the evaporator to the accumulator where it changes to the rubber part - lots of flourescence on this rubber line. Second - there is a leak at the front end of the compressor.

We'll see what happens when I make the appointment....
