Hi Guys,
I know it's a little warm to be using the heater this time of year but it was a bit nippy last night in western MD. I have no heat. I troubleshot it today and I finally got heat when I disconnected the connector to the heater valves. I know that no juice to them means that the valves open. I noticed that there was constant 12v to the solenoids which was not letting hot coolant to flow to the heater core. I read a few previous threads and noticed that shogun suggested to check it ihka control panel and ihka control module. Where is the ihka control module?
I can also hear the auxiliary pump when it kicks on. It makes an annoying hum that I can hear inside the cabin. I may have to replace it to quiet it down.
Assuming that I got heat when I disconnected the valves means that the valves are ok, right? It seems that the ihka control module is the culprit.
Please help,
