Air conditioning heater fan in your l999 vw beetle stopped working any suggestions fuses have been checked where are the relays?

I am not a mechanic, but I just had this problem with my a/c. I checked all of the fuses -- no problems. I pulled apart the instrument panel to check the connections to the switches -- no problems. My next step was going to be to remove the panel that covers the blower (under the glove box) and check the connections on that end. Before I got to that another issue came up and I took it to a mechanic to solve all issues. Turns out, my next step would have solved it because they found that the connection to the blower was loose. So, that may be your issue too. If you have already checked the fuses, I recommend that you start with the blower rather than the switches behind the instrument panel (it is really a pain to take apart and put back together). Hope this helps.
