My daughter’s 2005 beetle convertible 2.0L A/C started blowing “warm” air a few weeks ago. My first thought was that it needed a recharge. I hooked up a can of ACPro and the pressure gauge indicated the system was fully pressurized so I didn’t add anything to avoid over-pressurizing the system. After some searching on the interwebs, I noticed that the fans aren’t coming on either, which led me to the infamous fuse box on top of the battery which was damaged/melted where the alternator harness connects. I just finished replacing the alternator harness and fuse box but still warm air and no fans. I borrowed a friends multimeter, and though I have no clue really how to use it, tested a few things and noticed that there seems to be no voltage in the fuse box at the fan control module connection, but not really sure what that means. Also, the voltage at the alternator harness connection was 16+ volts which seemed to be high based on what I’ve read but not sure if I was even taking the reading correctly. Please help!! I can’t really afford taking to a mechanic so any helpful advice would be greatly appreciated.
Update: Today I correctly re-checked the voltage. The battery as well as every connection of the fuse box was reading 14.23V while the car was running. Still no fan when the engine gets warm, or when the AC is on. Any suggestions?
