Hello guys,i'm having problems with my blower control switch..I can get the switch to blow low and mid but when i switch it to high nothing happens..So the question is could my switch be bad or could it be something else.. Oh almost forgot it's a 1984 Delta88.. Thanks in advance..

 

It's not the switch.

Check the high speed relay and fuse, and the associated connections.

The '84 is later than the cars I'm used to, but those parts will be there somewhere.
