Hello my truck runs great but the A/C / Heat control only works on HIGH!! I think I'm going to change out the control unit . How does that sound??? THANKS!! Oh also the turn signals ,when activated left/ right set the hazards off?!?! Spooky
Other than the computer and seat module issues it is a great truck.
