My friend has a '99 VW Golf.

A/C does not blow.

checked the blower moter.

there's what looks to be a sensor under the blower motor, he calls it a relay. looks horrible.

along with that, what other componets should be tested to get ait blowing?

maybe, heater contoler?, i looked under drivers side for fuses, all good. i dont know where the other fuses and relays are.

any suggestion for a fix?

i'll have the car thursday to work on it, pictures would be very helpfull because i know nothing about this car.
