Where is the fuse for a 1989 Ford Festiva heater blower?

The 1989 Ford Festiva heater blower fuse isn't in a single, easily-identifiable location like a dedicated "blower" fuse. Instead, it's likely part of a larger circuit protected by a fuse in the fuse box (often under the dash or in the engine compartment).

You'll need to consult your owner's manual. It will have a fuse diagram showing which fuse(s) are responsible for the blower motor. The diagram will specify the amperage rating and location of each fuse.

If you don't have the manual, you can try these steps:

1. Locate the fuse boxes: Check under the hood and under the dashboard. The under-dash fuse box is usually accessible by removing a cover.

2. Inspect the fuses: Carefully examine each fuse for a blown element (a broken wire inside the glass). A blown fuse will appear dark or broken. Do not touch the metal parts of a fuse.

3. Check the fuse amperage: Compare the fuse amperage to the rating specified in your owner's manual or online repair guide for your 1989 Ford Festiva. (Some online parts sites show diagrams)

4. Consider the resistor: If the fuses are good, the problem might lie within the blower motor resistor. This is a common point of failure for blower motors.

Caution: Always disconnect the negative battery terminal before working on the electrical system of your vehicle.

Without the owner's manual, pinpoint accuracy is impossible. The fuse box diagram is your essential guide.
