Back again with climate control issues. Last year the heat would stop working but if I stopped and shut everything off then restarted it the heat would come back on.
This year its a new problem I'm getting heat to the passenger side only. I have replaced the auxillary water pump and that didn't fix it. I have also rebuilt the monovalve. I suspect it is a vacuum problem but have no idea where to start. Is there a step by step guide to trouble shooting these systems? I'm the type that needs words and pictures.
