Nick - I don't think using the thermostat to control the blower motor would work.  I think that it could turn the motor off too soon.  If you look in this doc http://www.techwebasto.com/heater_main/LIT699745A.pdf on page 19, it looks like the blower motor runs for a while after the fuel is shut off, probably to cool the combustion chamber and purge any unburned fuel vapors.  I think you could have a case where the Webasto is still firing to heat the water and the thermostat would shut it down. The Webasto cycle isn't really controlled by the thermostat in the coach, it fires on and off to keep the circulating water at a certain temp until the thermostat in the coach says it's warm enough, then the webasto goes through a shutdown cycle, which keeps the blower running for a while. 

Maybe the relays are made by Hella, I'll do some scouting around...

Steve,

You are correct. The unit does go thru a cool down cycle after it is shut off. I have had a little luck talking to a tech at Webasto. He is also going to check his personal parts for something that could help. He apparently does a little bit outside of work and was in the field for some time working on them.

Thanks,
Bryan

Hi Bryan and Steve,

Maybe the Webasto tech guy will give you a better price on a new module..

Funny, The Webasto people sent a regional supervisor to my shop today to interview me for being an authorized Dealer..

I will know in 2 weeks!   If so, I will be able to reduce that high price for the module.....

Nick,

That would be a good if you could get set up as a dealer. The tech can't do anything on new parts  Sad but maybe has something in the good used.
I may have found a used 12v unit that quit working and the guy bought a new one. If he did not chuck it it might have a good relay  Shocked

As I was typing this I talked with a guy I know at United Diesel. He quoted me a new one for a really good price. I will probably get it if I cant fix this one.

I will keep hunting for a little while.

YOU might try calling Dave haynes at vehicle systems (Aquahot, Hydrohot). They use the Webasto head in their units. Might have a dead control box.

Unfortunately, they let Dave and many others go several months ago.  Not sure who is left there.

That is a terrible loss for many of us.  

The story I got was that after the owner was murdered in January , there was no funds left to keep the staff.  He had been keeping the company going out of his own pocket.  From what I have heard, he was a great guy.

I just did a search and was very surprised to hear that Hap's daughter has been charged with the murder:  http://www.denverpost.com/news/ci_11805248

I am not saying that they are tanking, just that they had to cut way back.

Jim,

That's terrible news. I had not heard that the owner had been murdered.

I had never met him. I did meet Dave once. He gave me a tour of the facility several years ago and did help me with
understanding my AquaHot B model.

Sorry that this thread has taken a bit of a turn, but I wanted to make one more statement about Dave Haynes.  He was/is a one of a kind.  He had some pretty significant health problems and you would never know it.  He was ALWAYS willing to go above and beyond for any customer - even us one-off customers. 

I am pretty sure I have his private number and have wanted to talk to him, but could never find the spare time.

Thanks Clifford. I sent them an email and will try to call tomorrow. I had seen that they were a Webasto dealer a while back but it did not cross my mind.

Good News- John at Bus Services has the relay I need and is shipping it out today for $10.00 + shipping  Grin
Hopefully that will get me back in business to bench test!

Thanks for all the help guys! I sure do appreciate it. I am almost a certified Webasto tech now  Wink Almost!

I will update you when I get the new relay soldered in.

Just thought I would let you guys know that have not dealt with John at Bus Services. He is a heck of a nice guy. He was going to send me the relay for $10. Well he could not find his box of relays so is sending me a complete used control unit for the same $10. He did say the box had some electrolysis on it but it may still be a good unit. If not at least the relay would hopefully be good.

I might get lucky and it works fine, I hope  Grin

Brian that is great news!
It's awesome to hear of great people doing things like that! Especially these days when it seems that everyone is only concerned about the all mighty $ 1st, then anything else after word!

FWIW I too have been blessed twice this past week with awesome offers from 2 great busnuts who are trying to help us weather out the tough times! (more details and proper credit where credit due later!)
