Yea and even avoid recirculating if it's extremely humid.

So you're saying to only run the AC on 3 or 4 when you're recirculating?

It?s 134 and it?s not as cold.

 

Don?t run the system on low fan settings on recycle air or you will freeze
the coils

 

The noise is probably just the expansion valve and I think it?s normal.

 

Gauges on the system are the only way to check the system for low Freon with
134.

This is on the 2005 MSM. We have only heard it a few times so it is really
hard to diagnose. You can let the car idle and listen to the A/C kick on and
off. Every now and then (maybe 1 out of every 20 times) you can hear it go
"whoooooop" when it kicks on. The noise sounds like a rubbing noise (think
of a squeegee moving across dry glass) and seems to be coming from under the
dash. I do not know if a door opens and closes when the A/C kicks on or not.
Any ideas?

Also, the A/C does not feel "ice cold". How can you tell if you need a
charge on the new systems?
