Where is the rear AC blower located in a 1993 Ford Econoline with Mark III conversion package?

There's no single definitive answer to where the rear AC blower is located in a 1993 Ford Econoline with a Mark III conversion package. The exact location depends heavily on the specific Mark III conversion done by the manufacturer (e.g., Winnebago, Fleetwood, etc.). These conversions often varied in their layouts.

Your best bet is to:

1. Consult your owner's manual: The manual *might* have a diagram showing the location of components, including the rear AC blower.

2. Check the conversion manufacturer's documentation: If you know the original conversion manufacturer (look for a sticker or plate inside the van), their website or archived documentation *might* have service manuals or diagrams.

3. Visual Inspection (Safely!): With the van's power off, carefully examine the areas under the rear seats, behind the rear paneling, and in the rear storage compartments. Listen for the blower's motor sound when the rear AC is switched on (if it works) to help narrow down its location. Be mindful of sharp edges and potentially exposed wiring.

4. Use a flashlight and mirror: Reaching into tight spaces might be necessary, but safety is paramount.

Unfortunately, without knowing the specific Mark III conversion company, it's impossible to pinpoint the exact location. The blower motor could be in a variety of places depending on the van's design and how the manufacturer integrated the AC system.
