2010 Volkswagen Jetta Q&A
2010 Volkswagen Jetta Question: 2010 Jetta with 2.5 engine, the a/c it taking too long to blow cold air.
the low speed sensor for your fan may not be working. I'm guessing when the high speed fan turns on when the engine it hot enough, then the a/c works too because the A/C wiring is also connected to the fan. - freshapple
