Interesting A/C Problem

You are on the right path getting it recovered, vacuumed and charged to the proper level. The E53 platform only takes 0.98 lbs of refrigerant and can be temperamental with off amounts. A bit low and the right side blows warmer, a bit high and the evaporator can freeze on highway trips... Good first step is ensuring proper charge levels with most AC problems.

Well that is a relief. Do you think it could use a small amount more as a test before recovering and fully servicing the system? I always err on the side of conservative (and if it ain't broke, don't fix it) so I stopped before I got to a psi level I was not comfortable with.

If you think that it could use a small amount more and that it could cure the difference in temp side to side then I would be happy to try it out.

Also, I am mostly concerned about the noise in the dash that is affected by my wonky mixture dial and the lack of volume from the vents. I think I will order a FSR today as well.
