Hi all,
I can't get any heat out of the divers side. The passenger side is ok. The electric water pump runs when the temp dial is truned to heat but only one of the lines to the heater core (presumably the passenger heater core) gets hot. I guess there is either an electical fault or a fault with the heater valve.

Does anyone know the procedure to hotwire the valve to open? I can see there is a connector of sorts on the valve/pump block but don't want to just start probing with 12v unitl I can confirm what I should be doing.

Are there any other common heater failures to look for?

Cheers
