my 93 caprice isnt blowing any heat, ive replaced the thermostat, heater core, blower motor, and all the resistors, its not clogged anywhere... so i need a little help on why theres no heat, ive been told the door might not be opening all the way so first i need to know where that is located thank...

 

They are located under the dash. Not sure exactly where under the dash on a 93.

 

thanks i found the problem the door wasnt opening enough but its fixed now lol
