Check your actuators on the heater box, i'll send a generic pic along. They are either vacuum or electric and you'll need to check if you are getting power or vacuum to them.

Checked manuals at library couldn't find anything about actuators check parts store parts available heater control valve and blend door actuator which is electrical. From looking at the pics the heater box needs to come down. Can you give some instructions?

Thanks for the instructions a major job my owner's manual has a chart for the fuse box on the side of the dash but only found the back blower there. Is there a chart for the main fuse box in the engine compartment?
