My 34' 2005 coach has 2 zones for the AC the front does not seem to be blowing cold air. The rear AC unit zone 2 is very cold. Couple that with the dash air not blowing very cold air and the front of the coach is pretty hot you could hang meat in the bedroom in the back. I figure I probably need a new unit but was wondering if there is anything I can check?If I do need a new unit is this a DIY job or is it something that needs to be done at an RV shop? I have DIY skills and a forklift to load unload the AC unit and a background in mechanical and electrical but I am not an RV tech.I plan to have the dash air looked at. I also noticed the dash heat in the winter did not work well. The valves in the heater lines are turned on right now. I plan to turn them off and try the dash air again before having it worked on.Thanks MikeHave a happy fathers day!!

I found this on youtube I am going to do some checking. https://www.youtube.com/watch?v=yl-f71tj8VA

Is this a single unit basement A/C ?This could be a ductwork flap problemOr A #2 compressor problemYou need some one to look atModel# and Mfg brand info, will get you more answers and probably better

Neither one of mine are working right now. I can hear the compressor kick on when going from fan to ac. Im going to braze in a service port pull a vacuum and fill with r22 and see how it goes. If not will have to replace both.

Sounds like you can do it yourself and you have the stuff to do it with. Change both of ours a few years back along with new Thermostat. No issues. enjoy

I have been playing around with it and it does seem to put out cold air just not very much, it doesn't seem to make any difference on fan speed the amount of air does not change. I have taken the top off of it and looked for any blockage it all seems clear and it is not as dirty as I would have thought. It may be a fan relay or the fan motor is tired. I am letting it run again to make sure the coil is getting cold.
