Driving in the cold recently I noticed the cabin heater had stopped working. It eventually started working again after a while, though the output is not great. Engine temps seem normal on the gauge, coolant level is as expected.
I had a poke around with a warm engine last weekend. The feed coolant hose is hot, both sides of the valve. Warm on the return. Valve control seems fine as I could see it move and the temperature was the same both sides.
I'm thinking this probably means blocked matrix? I had a look in my Hayne manual and it suggests I'll need to get the A/C degassed and remove the evaporator to change the matrix. Anyone done his and know what the score is?
