* Under the hood in the fuse box: Many Ford vehicles of that era place relays in the under-hood fuse box/power distribution center. This is the most common location. Open the fuse box cover and look for a diagram on the inside cover itself. This diagram should show the location of the blower motor relay. The relay itself will likely be labeled or its function will be clear from the diagram.
* Inside the passenger compartment fuse box (under the dash): Some models place some relays inside the fuse panel under the dash. Again, consult the diagram on the fuse box cover.
* Behind the glovebox: Less common, but possible, that some relays were located behind the glove box.
To find it effectively:
1. Consult your owner's manual: This is your first and best resource. It should have a fuse and relay diagram.
2. Locate fuse box diagrams: If you don't have the manual, search online for "1992 Ford E-150 fuse box diagram." Many websites offer these diagrams. Note that they may vary slightly depending on options.
3. Visually inspect: Once you've located the fuse boxes (both under the hood and under the dash), carefully examine the relays. Many are square or rectangular and may have numbers or symbols on them. You might even find one labelled as the "blower motor" or a similar designation.
If you can't find it after checking these locations, a local mechanic or auto parts store might be able to help. Providing your van's specific trim level (e.g., Econoline, XLT) might assist them in providing a more precise answer.
