92 Dodge Dynasty No AC during acceleration Sign up here!

Sound like a vaccum cut out. Air blows somewhere else but not through the vents. Easing up on the accelerator, the air returns back to normal. Rick D Tom Greenleaf Ultimate Carjunky / Moderator Jul 29, 2008, 12:39 AM Post #2 of 4 (3151 views) Re: 92 Dodge Dynasty No AC during acceleration Sign In Many vehicles use engine manifold vacuum to change and hold actuator doors in position and when vacuum isn't available or leaking thru a hose or storage can of sorts they will default to "defrost'' ducts till vacuum is available again which is greater at idle, low speed and load or decellerating. You should look for vacuum leaks underhood as the likely source of this problem, T way2old Veteran / Moderator Jul 29, 2008, 4:25 AM Post #3 of 4 (3149 views) Re: 92 Dodge Dynasty No AC during acceleration Sign In Somewhere in the syatem will be a check valve. It holds vacuum as Tom described under conditions of low engine vacuum, such as acceleration. Click on this link for a generic picture of one. Being way2old is why I need help from younger minds Guest Anonymous Poster rdrake51@yahoo.com Jul 29, 2008, 7:23 PM Post #4 of 4 (3136 views) Re: 92 Dodge Dynasty No AC during acceleration Sign In Thank you very much for the info.
