Hey anyone with a 122, could you explain what I might expect from my heater fan? I can hear it working but don't really feel anything. Is this normal or do I have a filter somewhere that is blocked?

Filter... ohhh...my side...stop it!

No filter but flappers that might be malfunctioning and blocking air flow. From what I recall my fan never pushed a ton of air anyway...not like the 240 or 740, that's for certain...

Ya, the vanes in that motor sort of gently stir the air more than blow. On mine it was more than enough to keep things comfortable inside, but do check the flapper position. Make sure the plumbing is hooked up under the dash. The vanes on the fan do brake - so pull the motor and check their function (there's something you'll never hear a 240 owner say).

A TON of dirt and leaves could be sitting on top of your heater core too. When you've got the fan out you can verify this.

LOL @ 240 heater fan reference!

Will do.
