I have a 1993-1994 Blazer,
There is like 5 fan speeds, it gets up to hte second to highest but, then when i click it all the way up it will stay in the second highest one.
Has anyone had the same problem im having?
Thanks in advanced.

 

I'm not sure if there is a blower control resistor pack on the earlier blazers, but I know on the previous body style Wbodies (Grand Prix, Regal, Impala) had issues with the blower motor resistor pack where it would only work on high or low, but nothing in between. This sounds like it may be the switch in the dash, but I'd have to see some wiring diagrams to know what would be at fault and I don't have any wiring diagrams going back that far.

 

We have owned the truck since it was brand new on the lot(my moms truck, now mine) and it just started doing this recently.
