Dash heater control won't work

September 11, 2020, 11:33:30 pm

The dash heater control isn't working. It has been slow to get to work and now it doesn't work. It is an electrical control and the only way I can see to get at it is to pull the headlights. I don't know yet if it is the switch or the controller. Anybody worked on it.

Fan control or hot and cold control? My '99 looks like a Ford product as far as positions go.

Does anyone have a wiring diagram for the heater temperature control. I ordered all the diagrams from Foretravel for the
computer but I can see I am missing some.

I figgered out the wiring and I found the problem which was the electric plug on the controller. This is
why I redid the headlights now, so I could get at the contoller. It now is easy to get at and to remove
the new head light is a few minute job.

When  took the coach for a drive the other day and night the heater worked great. It had never worked right from the when I bought.
I thought is was just not a great heater so I guess the valve never got really open.

What did you have to do with the connector to get it working?  Having the same issue on a friends 99 U320.

I think I squeezed the connection with a vise grip and it that fails I will make up a new connector.

Our dash heat was getting slow to change temp... sometimes it would take over 10 minutes after adjusting the knob setting. After verifying a good connection at the control valve plug I determined the valve was hanging up. I replaced it with a new valve 
Thermotion. 4-Port, Electronic Heater Control Valve - P/N: 354-69494 - (5/8") It works good now.
