I have seen a lot of cycling switches malfunction. It's located on the accumulator, (long cylinder at passenger side firewall). When the a/c is blowing warm, see if the compressor clutch is engaged. If not, tap on and wiggle the connector of the switch and see if the clutch engages.

There is also a bulletin (#02-01-38-007) It explains some additional a/c performance checks for the tech to do for a poor a/c performance complaint.

SUBMAN, there are no a/c recalls for the 03 XL. There is a bulletin for poor a/c performance at idle or in traffic. (#01-01-39-004A ) The fix is to install an auxiliary electric fan.


If anyone want's to check your vehicle for recalls you can post or PM me your VIN and I can check for open recalls and warranty history.
