Heater Blowers

[hoodedreeper]

When the heater/blowers are set to the face on the controls....the 2 far side ones blow out hot air.But the 2 middle ones are still cold.

I presume my heater matrix has gone and needs replacing?

its not the heater part, the motor and rad are fine, it will be a problem with the valves, they might be blocked or something
