blowing fuses on 1990 Chevrolet Blazer

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When going from vent to off I blow a fuse. What could be causing this problem?
(1) Answer
Short circuit in mode selector switch in the control panel. Part prob. discontinued. You can check. AC and other controls work ok?



Update! Try NAPA part # TEM 207465. AC mode selector switch. That lever activates this switch, will need to remove the heater control panel to replace it. Not a hard fix if a little car savvy.
