Where is the fuse that controls blower motor on a 1998 Chevy truck?

The fuse for the blower motor in a 1998 Chevy truck is not consistently located in one single place across all models. It could be in the underhood fuse box, the under-dash fuse panel, or even an inline fuse near the blower motor itself.

To find it, you need to consult your owner's manual. The manual will have a diagram of the fuse boxes showing the location and amperage of each fuse. Look for a fuse labeled "blower motor," "heater," "HVAC," or something similar.

If you don't have the owner's manual, you can often find a free PDF version online by searching for "[your truck's model and trim] owner's manual PDF." Be sure to specify the year (1998) and the exact model (e.g., Silverado, C1500, etc.).

Without that manual or a specific model, giving a precise location is impossible.
