heat only sometimes

Hi there,

I'm brand new to the forum (and to owning a Tacoma) so my apologies if this has been answered elsewhere.

I just got an 06 TRD, and like it a lot. But I noticed today that I only get warm air from the vents when the engine is revving. If I'm idling at a stoplight for awhile, or when I start coasting/braking to a stop, the air coming out slowly cools off entirely. Once I'm moving, the air warms back up. Any ideas why this would be?

Thanks in advance!

 

my guess is you got a air bubble in there somewhere. put truck on ramps or uphill slant and burp that bad boy

 

Thanks for the quick reply, Steve. I'll give it a try!

 

Does your Engine temp vary ??? If So Possible Stuck Thermostat ??? If not Possible air lock. Possible Blocked heater core ??? (Try a flush ?)

 

Thanks for the ideas, Canufixit. Engine temp has been constant. I'll try getting any air out of the system and hopefully that does the trick!
