  Q: How do you remove the heater/air conditioning control unit from Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

  A: To remove the A/C switch from a 1994-1997 vehicle, start by disconnecting the battery cable from the negative battery terminal. Then, remove the instrument panel bezel to access the mounting screws for the A/C switch. There are four screws holding the switch to the dash, and they may need to be loosened if they are linked to the radio panel. Once the screws are removed, pull the switch out just enough to disconnect the control panel light, blower speed switch, and vacuum lines (if applicable). To install the A/C switch, simply reverse the removal procedure. For a 1998 and later vehicle, start by removing the knee bolster trim plate attaching screws, as well as the instrument panel trim plate screws. Gently pry the trim plate away from the dash and disconnect all electrical harnesses. Remove the switch attaching screws and disconnect the vacuum and electrical connections. Installation is the reverse of removal.
