Hi guys. Got a problem with my EB V8 heater. Yeah, you guessed it, its not heating. I got as far as checking out the plumbing and that appears to be funtioning, the hoses are hot.
I believe the problem lies with the blend door.
It could be blocked, or the blend door motor is cactus.
Trouble is I can't find out how to put the climate control unit into diagnostic mode.It could also be possible some junk is stopping the blend door from getting full open/closed, in which case I believe I should get an E2 error. Apparently, a simple reset might get it going again.
Of course, if the door is busted, it won't fix it.

Does anyone know how to run the diagnostic on the climate control and do a reset?

Sorry for wasting your time guys, I finally found it in the tech docs.
I did look there first, but I missed it.

My bad.

But I didn't get any error codes (ran test twice), and I still dont have heat. Got me stuffed.
