I think Barry did the same exact thing. He found a plug out that was heating up his cab.Billm said:I just found out why my knee kept cooking even after I disconnected the water hoses to the heater (which helped but didn't stop the heat). I found after I pulled out all of the carpeting to dry it that the rubber plug for filling the transmission was only partly plugged in! Once I fitted it properly the heat stopped! Only a week late.
