We have a 2007 Winn Voyage 38J on a Workhorse chassis. We had dash AC problems and got it serviced. Shop says they also had to replace an air box actuator. Good news is air is cold now but doesn't come out where I expect it to. I am wondering if they connected the actuator back correctly. It is a 3-position actuator on driver side of engine just under the wind shield deck that has 2 hoses attached to it, a red one and a white one. Currently the red is on the end, and white on the side of the actuator. Can anyone confirm if this connection matches theirs? I can try swapping and see if it improves but hard to get to, I don't want to do it unless I know that's the problem. I can also try to call Winn tech service but concerned they may not know this detail and send me to Workhorse. Thanks

1. Workhorse does NOT install the Dash AC system. Winne(OEM) installs the controls. They are aftermarket NOT a Workhorse Part. The only thing the chassis makers supply is the Compressor and those hoses and the Condenser.
2. Odds are you have a Evans Tempcon system. This is the link for their systems and troubleshooting. Doug

Sounds like it went in for one problem and came out with another. I'd have the shop make it work like it should at their cost.

Agree it would be at no cost but there's our hassle factor of taking MH back and dealing with them. If it is easy it is worth it to me to do it myself, plus I learn something too.

With more research I found this helpful Winn Service Tips link regarding my situation. We have the rotary control style system. Appears my vacuum hoses are connected properly.

My concern at this point would be that they installed the incorrect actuator and it's not getting the right signal from your controls.
