    Get yourself an OBD-II cable, a copy of VCDS-lite, and scan Climatronic for codes.

    if the blower doesn't come on when you want it to, give the glove box area of the dash a thump with your hand. If the blower kicks into life then your brushes in the blower are worn. This is a VERY common fault. I sold thousands of replacements brushes in the UK. I no longer sell them but they are still widely available in the UK on ebay. If you dont want to order brushes from the uk, get a similar sized set of carbon brushes from a power tool etc and chop them down. You can also pull your old brushes out of your blower motor and rotate them through 180 degrees. The taper on the end is then reversed and this is regularly enough to get the blower working again temporarily.

    Hope this helps

    The brushes might be worn, but don't rotate them 180 degrees, that can damage the commutator, and wouldn't last long anyway.

    Check fault codes and post results.
    See this self diagnostic test. (Read second paragraph before using)

    NOTE: Actuator test: Should read, Battery Voltage >11.5 <15.5V.

    The self diagnostics might not work because of the fault. If not, use VCDS.
