This post may be in the wrong forum but I hope someone reading it will respond and point me in the right direction.

I have a 1999 Ford E150 Conversion Van by Coachman. Recently the rear air conditioner stopped working. No cooling - no fan. This also killed the front air conditioning although the front fan still works.

Fortunately I found a local shop that was able to find and weld a pin hole in one of the coolant lines in the rear unit so the air has been restored to the van.

At this time the blower for the rear unit will not run. The shop determined the blower would run if supplied with current but was not able to do anything else as they did not know much about this model.

I have heard there is some kind of air conditioner relay in the engine compartment that might be the problem.

Does anyone know where it is located, how to recognize it, and whether it is a repairable item or one that must be replaced?

This is my first post to this forum so I hoping if this question is in the wrong place it doesn't create a problem

 

You might try tracing the color of the wire that provides power to the rear blower motor and look for that particular color wire on the relays you see. They don't usually use the same color for multiple functions so it might help if you looked for that color and see what you can come up with. One of the relays should have that color coming off of the relay.
