You named off four things there that should have power. Which on doesn't? The A/C compressor(a/c), the blower motor fan(fan), the engine coolant fan/s(fan), or the heater/A/C control module in the dash? I suspect you have a bad blower motor resistor.
first turn off radio to keep from locking it out then remove the negative battery cable.now to remove blower motor on blazer go under the hood remove pcm computer from the top of the coolant recovery tank,then remove the coolant recovery tank your heater blower motor behind the housing remove blower motor electrical connectors then remove blower motor housing bolts then you right at the blower motor.
YOU NEED TO TURN OFF RADIO TO KEEP FROM LOSING RADIO CODE.REMOVE NEGATIVE BATTERY CABLE.THAT WILL DISABLE AIR BAGS.WAIT 30 MINUTES.SO THE AIR BAGS CAN DISCHARGE.THE BLOWER MOTOR IS LOCATED ON THE PASSENGER SIDE OF VECHICLE UNDER THE INSTRUMENT PANEL.WHEN REPLACING THE BLOWER MOTOR.YOU HAVE TO REMOVE THE SQUIRREL CAGE OR BLOWER MOTOR FAN.BY REMOVING THE METAL STAR CLIP RETAINING THE FAN CAGE TO THE MOTOR SHAFT.REMOVE THE FAN BY PULLING STRAIGHT OUT.TO INSTALL BLOWER FAN TO NEW BLOWER MOTOR.INSTALL THE FAN CAGE ONTO THE MOTOR SHAFT .ADJUST THE FAN CAGE TO GET A CLEARANCE OF 0.30 INCH TO THE MOTOR MOUNT PLATE.INSTALL EVERYTHING VISA VERSA.BESURE TO BUY A REPAIR MANUAL.SO IT CAN SHOW YOU WHERE ALL YOUR PARTS AND SCREWS ARE LOCATED. WARNING IF YOU HAVE ANY DOUBT ABOUT THIS TASK.LET THE DEALERSHIP DO IT.
remove the passenger side lower insulator panel. behind the panel you wil find the blower motor housing. next to the blower motor housing there will be a wiring connector with 6 to 8 wires going in to it. the connector will be held secure with 2 screws. remove the connector and remove the screws -- this is your resistor. reverse the process to re-install.
