My interior fan speed control for A/C doesn't work at 1&2 step.It is working OK on 3&4 but in side is getting too cold :unsure: I have checked the control switch and it is OK.I could not find the speed control module.Does any body know where it is and how it looks? My car is Galaxy 1999,115Hp,2000 DOHC,regular A/C(no climatronic) Regards, Stoy@n
