blower goes out on 2000 ford econoline van 4.2L E-150 during acceleration


Asked by Jul 23, 2013 at 11:32 AM about the 2000 Ford Econoline Wagon 3 Dr E-150 Chateau Passenger Van

Question type: Maintenance & Repair

1 Answer

Tracy Hooks

I'm willing to bet that the fan doesn't stop but is diverted to the Defrost mode. There is a vacuum line that runs from or near the intake manifold to the right front of the van. It has a "T" that connects to a check valve and a vacuum reservoir. Either the check valve isn't holding or the vacuum reservoir is leaking. It's designed to keep the AC wherever you set it during hill climbing or hard acceleration.
