Question for 96 Dodge Ram owners
My question is: What the hell would cause the air conditioning to turn off when you apply gas and then turn back on after you let go of the gas? This is about to drive me crazy and its very annoying....
I changed the freon or refilled it.... it worked for a little bit but afterwards the problem came back.... Please help me
thanks

RE: Question for 96 Dodge Ram owners
This is the 'Wild Vents' problem that is due either to a vacuum leak in the cruise control hoses below the battery tray - or to a problem with the check valve on the passenger side of the intake manifold.
here's an old post:
----
I had ordered a replacement part from Dodge that is supposed to correct the
'Wild Vents' problem. This is where AC/Heat air blowing out vents
mysteriously changes and comes out other vents. It is most prone to happen
when accelerating. I read that the cruise control can suddenly 'pop out' of
setting too.
I haven't had the vents change wildly like that myself, but I have had the
'Defrost' setting refuse to work, then come on suddenly 10-15 minutes later.
Chrysler's 'Fix' is replacement part number 04677204.
I think there is a TSB on this.
I had seen the description of the problem in some automotive service
magazines.
My local Dodge dealer told me they now had the part, and I went and picked it
up (plus a broken passenger side sun visor clip). Cost was $7.84
The replacement part turns out to be about the size of a 35 mm Film can and is
a small vacuum reservoir with a built in check valve.
The original part (4306923) was a tiny check valve about the size of the tip
of my thumb. These check valves are in the vacuum line connected to the
nipple just rearward of where the PCV valve hose connects on the passenger
side of the engine. Just behind this check valve the vacuum line T's off that
goes to the cruise control mounted underneath the battery.
But when I went to put it on, I found that the new part lacked the proper
rubber hose fittings to install it. The new valve 4677204 has 3/16 nipples.
The new valve comes with only one rubber reducing elbow which has a female 3/8
end, and the other end 3/16 female.
The original check valve 4306923 has 1/4 plastic nipple ends and has a 1/4
rubber female elbow on one end, and short length of 1/4 rubber hose on the
other. The new valve's 3/8 rubber elbow is wrong - too big to seal to the 1/4
nipple at the intake manifold.
I went back to the Dodge parts counter to ask for the proper rubber fitting to
make it work, but they said they didn't have them and suggested I would have
to go to a parts store. At the local Advance Auto I could not find exactly
the right fittings, but was able to put the new check valve on using slightly
smaller fittings:
Motormite Mfg. Vacu-Tite! pn 47411 rubber elbow with 9/64 and 7/32 id ends,
and Motormite Vacu-Tite pn 47411 rubber straight with 9/64 and 5/32 id ends.
Seems sloppy on Chrysler's part - but maybe later model Rams than a 1995 have
different sized vacuum hoses and manifold fittings ?

RE: Question for 96 Dodge Ram owners
When driving the A/C is working fine, blowing cold air and everything is good to go. But if I need to accelerate thats when the A/C cuts off and then back on after I release the gas. It cuts off totally until I let go of the gas ... I dont know what the problem is, all i know is that I re fill the freon and that didnt work. This never happen before until now...
