If all the windows are not working from any location in the truck then your probably looking at a fuse but if its just one window or from one location ,for example back window works from drivers seat but not from back window door , then your dealing with a switch or wiring issue. If you could be more specific as to what works and what doesn't it could help. Are all windows not working or just one or two?

None of the windows go up or down nor the door locks!!!
No power to fuses!
My issue becomes multiple. When the window switches don't work, the heater meter shuts down ,as well as the cruise control,all at the same time they quit working.??

Hi @myersw835
Couldn’t find the wiring diagram for a 1989 Blazer, but here’s an image showing the wiring for the doors locks and windows from a 1988 wiring diagram found here. Hopefully the 1989 wiring is the same as the 1988
It doesn’t show any fuses as such but circuit breakers. It would seem strange that neither would have power to them as the door lock circuit should be powered all the time and the windows would be only when the ignition key was operated i.e. two distinct power feeds.
You may have to trace the wiring back from the two circuit breakers to see if there is a common point.
(click on image to enlarge for better viewing).
Note: I checked the wiring diagram for the 1991 model and it shows the wiring for a 2-door and 4 door model for the door locks whereas the 1988 wiring diagram is only for a 2-door model and they are the same, but the 1991 diagrams don’t show the power windows wiring
Hopefully this is of some help.

My driver side window will not work. For 4 +years I have been able to use it, but it would work very slow to go up or down when it worked. It's down now, but it will not work at all.
