Did you do any work under the dash, about inline with the steering wheel column ?

I ask as the flasher and the blower motor relay are both in the same aux hold ( I think still on your MY truck, I know '01 - 03 it is ).

Under the dash you would be looking for this about inline with the steering wheel column.



Sounds like the aux relay block might be missing a ground ( again if this is still the same on 97-00 MY trucks, should be ).

Take a look under the dash in that area, and see if a connector is part pulled apart, or if a ground is missing from it.

Sorry best SWAG I can come up with right now.
