Answer #1
irvtech March 26, 2009, 21:18JourneymanWhen the AC does not come on and the system is fully charged, there is usually a fault. First thing, if the faults were not cleared from the system after it was recharged this can happen. You need to find a shop that has the proper tools to scan for faults, log the faults, clear them, then recheck the operation. If the AC system does not work then, it should be retested, because it should reset a code for the areas causing the fault. Good luck.

That was replaced and everything kicked in. Probably could have continued to fill it with refrigerant once a year and just replace the sensor.

erigas August 12, 2009, 12:04ReplyRookieDo you the sensor name/part number that was replaced? I'm having the same problem with my 97 E320 and would like to replace the sensor first.
Thanks
