Any one know the fix for the dash vents only going to the front windshield. I have vacum coming from the vacum generator but it still only stays on the windshield, AC is cold etc. just vents not changing.This is a 2002 Holiday Rambler Ambassador diesel pusher only had it 6 monts. Any suggestion will be helpful.

Welcome to the forum!

I don't own a Monaco but had a similar problem with my Itasca and it was a hose going to a vacuum "ball".... a round, soft ball sized plastic unit mounted on the firewall near my generator.

Best of luck. Glad you found us.

You have a a vacuum problem. The AC is set to windshield default for safety. Check all vacuum hoses and the accumulator tank.

Agree with Ricko. My Itasca defaults to defrost when the vacuum is disturbed. My problem was a pinched vacuum hose. Once rerouted the problem was resolved.

Accumulator tank! That's the term I was looking for and could only come up with a "softball sized plastic ball".

Thanks

Thanks for your responses, I do have vacum at the accumulator one small hose going from accumulator to under the dash, which does have vacum at the accumulator have not found the other end under the dash yet.

It should go the the back of the heater-a/c selector on the dash.

Had a simular problem with a Coachmen Mirada. This one had a tv in the center of the dash at the bottom, not mounted above the windshield.

There was a small vacuum line running behind the tv that it had been set on and wore a hole in the tubing. I got to it by removing the tv.

Don't know what you have but near the right hand side of the dash, I had an actuator door that the vacuum tube attached to. Once I found that I traced back and found the bad spot in the tubing behind the TV. I fixed it by taking a slightly larger piece of tubing. Bought it at ACE hardware, cut the bad section out, heated the new tubing with my heat gun and slipped it over the old tube. The splice worked perfectly and I had dash air again

Its a tight fit under these dashes but if you can find where the tube from the accumulator goes to the actuator door you will probably have found your problem.

Hope this helps
Happy Trails

We have a 2000 HR Ambassador, the dash air was stuck on defrost. We traced the problem to the vac. Pump. We were able to get a replacement on eBay for $49.90 model: dorman 904-214 and pump connector/plug: motorcraft wpt-169 $30.94. We no longer have a problem. Hope this helps someone.

He said there was vacuum at the accumulator one should properly assume the pump is working.
