 Subject: Vent Control question
IP: Logged
Message:
Ive got a 95 dakota, and the vent control only allows air to blow out of the defrost vents. Does anyone have any ideas as to what the problem is before I go ripping into the dash. Is it something that can be fixed, orwill it require some new parts? Thanks a ton.

My '98 does that too. I don't get any air flow through the front vents. Air blows through the defroster fine.

its possible that you have a bad vent control switch.... but there vacuum lines that come off of that control head that go to vent actuators that control the blend doors.... im not sure on the process of getting to the vent actuators of the blend doors on driver27's 95 but for relf on your 98 you gotta pull the dash out to get to that vent actuator for that blend door that controls the defrost vents and your front vents.... if you dont pull the dash out you might be able to work around it but i went for the easy way cause i had to replace that actuator for the defrost and vent door.... it might look hard to pull that dash but its simple and easy... lower the steering column, disconnect the dash harness connectors there on the driverside, disconnet the heat and a/c controller, theres like 5 or 6 screws up near the windsheild and 2 bolts or nuts down at the kick panels..... should take ya about 30mins to pull it all out to get to that actuator for that blend door....

Before you rip everything out, double check the vacuum line that runs through the firewall for disconnection/cracks/holes.
If it doesn't fit, force it. If it breaks...well...it needed to be replaced anyway.

On the 95, you can easily reach the actuator on the driver side. look up near the gas pedal. On the passenger side I can't remember if it's easy to get to or not. I think you can remove the kick panel and reach it.
You can also take the dash face plate off and pull the HVAC unit. Check the vac line there. There's a single connection that plugs in that has the lines all coming together.
Does you cruise control work? It's vacuum operated too.
On the 95, the vac line runs through the firewall at the heater core just below the hoses. I had a problem with mine once on my old 95 and turned out the vac line from the HVAC unit was not plugged in correctly to the main system behind the TB.
Also, coming from the softball (pressure reg)on the passenger side, there's several vac lines that connect together in near the tb. There's a couple that are not rubber but some kind of harder plastic. Mine broke once, I just connected to two together using a small piece of rubber vac line hose.

this is happening to my 97 dakota v8...everything works fine but its stuck on defrost! now i look under the hood n the vac hose that runs along the firewall has a T splitter in it n the small lil vac hose that runs down is broken off and i cant find where it goes. i have been told this is the line that controls the HVAC controls! Where does it run through and can i just run a new hose directly from the back of the HVAC controls to this T instead of pulling the entire dash out to replace this lil annoying hose?
OR if anyone has a pic of where exactly the hose goes into the fire wall would help me out even more! if it is at the heater hose foam u think i can just cut around the foam and pull it out n cross my fingers the vac line is there?
Also on the back of the HVAC direction controls how many vac lines r there and wich one is the one that runs out to the engine bay?
thanks!

Same thing happened to my dodge Dakota 2000.
I just pulled the dash out, I blew on the vacuum connectors
To the knob where you turn the ac and I out it back and was
fine.
Try to take off the ac connector which is connected to the
vacuum lines to the ac box, blow on em and put it back.
Might work.
Otherwise ya gotta take the whole thing apart.
And yea u gotta flush coolant and disconnect ac line unless
ya can see the vacuum looking lines back there somewhere
by the ac box. Good luck guys. It's hella of a job.

Yeah what year is the truck?
And it's like a wire that pulls the vent open and pushes it to
close. It must have disconnected or the plastic connector
broke.

Little late to this, but I thought I'd share my info.
My 97 has been stuck on defrost due to a leak somewhere and I
found out it was the switch. For one, I could hear it leaking at a
high pitch behind the dash. Then, me being my "why not" self, I
pushed and pulled on the knob and when I pushed on it the
noise stopped. So, I pushed on the knob and held it on the front
vent setting, then sure enough the damn thing changed to the
front vents instead of the defrost. I'm sure by me pushing on it,
that sealed the leak inside the selector for that moment. It
usually will stay on too, until I turn off the truck or run it for a
long time.
Just something else to try to find out if it's the switch or not.

Message:
mine is a 2004 non-vacuum as well, and the problem seems
to be that the arm which comes from the controller to the
defrost vent does not connect to anything on the top end.
There appears to be a piece missing between the metal knob
on the end of the arm and the hole that goes into the vent
housing. If anybody knows what part goes there or where I
might get one, I'd love to hear it.

Just a thought, You could check with your local
dealer and see if you can't get a print out
(diagram) of the controls.

I have a 1999 Dakota...V6 w/ A/C. Also have fail mode on selector switch. I have removed and cleaned some light grease from the rubber wheel inside the selector. I have vacuum at the Black line, so that seems good. I found some of similar colored lines above the gas pedal with connections, but no idea where they go. Is there a diagram of the vacuum system for the Dakota?

The selector switch is vacuum controlled. The colored hoses (red, yellow, greeen, etc.) connection is under the dash and accessible. Verify that the connection is solid. Give the lines slight tugging under the dash to see if they're pinched. Also, listen for possible leack. If the vacuum is missing, the default position is defrost.
The fan speed is electrical. The temperature is a mechanical cable.
