E-350 SuperDuty fifteen passenger van.
when I take the access panel on the dashboard off, and expose the vent controls I am able to manually push the lever to change the vent set that the air blows out of, but of course it will not stay in that position for any longer than my hand is there.
so I have determined that the probable reason that the air conditioning is only coming out of the defrost vents by the windshield is due to a lack of vacuum pressure. My first problem is that I have been unable to locate the vacuum canister on this vehicle. Secondly, I am not really sure what to do once I find it, as I do not have any experience with vacuum systems. Any help on this would be greatly appreciated, as the Arizona heat is getting to be a bit unbearable.
have the same problem?
