hey guys my heater stopped working about a week ago or so and i was wondering if anyone knew why

899 sei
Thanks!

Do you mean heater or heater fan?

If heater, suspect that cooling system needs bleeding. (On Sei, with heater on full.) Possible water leak?

If fan, first check fuse.

Is your engine getting up to temperature?
(difficult to tell I know without a temperature gauge!)

If the engine is nicely warm, but the heater isn't, then the coolant valve on the Sei's heater is a likely suspect.

Unless you mean the heater fan isn't working.

As I found today, the outer of the valve adjustment cable can slip through the retaining spring clip.
