Hi all
Been browsing the forum for a while trying to get the bottom of this!
I’ve had no cabin heat for around a year now - was tepid but now completely cold.
Garage found a crack in the radiator and said no heat likely down to poor pressure (had to regularly add coolant)
That has now been replaced but still no heat.
Checked all relevant fuses but not sure how or what relays to check.
Engine gets to temp and all pipes in engine bay hot/warm to touch - including through the firewall.
Went on the hunt for the ‘heater blend actuator’ and found that to be moving freely when the temp dial was moved.
Blower works on all speeds but when I removed the panel to check actuator I noticed this weird water(?) stain which I think is directly in line with the blower resistor!
Any ideas on what it could be and whether there is something there that needs replacing?
