Webasto heating problem

[Deekers]

Hi,
We have 1989 40' with a DD 8V92. The hydronic heat circulates well but the problem is the internal fans will not come on. By design they are not supposed to until the circulating water/glycol reaches a warm/hot temperature.

I have checked all the relays, circuit breakers, diodes, etc. but to no avail. My next hope is too locate the thermostat that prevents the fans from coming on. The only problem is that I do not know where it is!

Additionally I have run many searches for diagrams or prior experience and even emailed Country Coach but they were little if no help for an older bus.

Any thoughts or suggestions, especially on the thermostat location, would be appreciated.

Not taking anything away from iRV2 but the forum in the following link is probably the best place to get your Webasto questions answered.

Thanks, I will also post there.

Problem solved! Used a wire tracer and a helpful suggestion from Oregon MotorHomes and I found the thermostat switch under the wardrobe. Jumper'ed it and the fans came on.
