C0048

When ac or heat was on at any speed, it would run for a few mins. Then stop blowing out air before slowly dying out. It would make noise like it was trying to work again, but then wouldn't. Took it to Mazda dealership. They did "test on ac/hvac system & found faulty control head due to electrical failure." they installed a heater control & the problem was fixed for a while. 3 months later same thing happened again. This time i was told the "hvac blower motor was tripping out on internal thermal overload" so they replaced the hvac blower motor. While that was getting fixed, i also had them look into another problem i was having. The tcs/dsc light would stay lit for 10-15 mins after i started my car and sometimes would just randomly come on while driving. The dealership did test & found "code C0034 - right front wheel speed sensor signal rate out of range & C0027, C0048 - right front wheel speed sensor circuit open, tech monitored sensor & found internal sensor failure. Corrected by anti-lock brake system. Installed gs3l-43-70x: right front abs sensor."
