I have a 2003 Chevy S10 Pickup, 4.3l V6. I'm trying to change the heater core. I have a Haynes Repair Manual. I have removed the dash. I've also removed the blower mower resistor screw to the heating/ventilation module as described in the repair manual. I'm now trying to remove the heating/ventilation module. The repair manual does not match what i see. The manual says remove the screws from the vehicle interior and remove the module. I've found one screw on the interior which does not loosen the module. While searching the web, I've found references for similar vehicles that you need to remove the front right fender, wheel and loosen screws in the engine compartment which go thru the firewall. Does anyone know the detailed steps to remove the heating/ventilation module on a 2004 Chevy s10 pu? thanks in advance for your time.
