Seems rather odd. I would suspect the actuator itself, but not entirely sure. Seems that the ECC is easier to get to. Do you know anyone with an ECC controller that could be swapped out for a test? That way you could eliminate the ECC possibility before going under the dash. Any other symptoms or problems also occuring?

The same exact thing is happening to my 98 Bonneville SSEi ! I obviously cant work on it myself and was wondering if this is a dealer thing or can I just take it to a garage to have it fixed? It seems like its going to be a pain in the *** to fix and probably cost me out the ***.

Bchick... we can walk you through it if you are willing to try. Honestly..most repairs are merely turning a bolt and replacing a part. In this case.. pulling out a glove box and looking at an actuator arm.

Ok, I was fooling around with the temperature control today while driving and put it down to 60degrees and then back up to 90degrees and the heat started blowing out?? Sooo, would this point more toward the control thingy or the actuator?

Probably a cracked gear in the actuator. Sounds familiar to what my car with a bad actuator did. Commanding full cold and then, full heat sometimes caused the actuator to drive left then right producing heat. Eventually, maybe even the next time you start it up, it will be back with no heat again. Then you try the full cold/full heat trick again, and sometimes it works, sometimes it doesn't.

The best way to confirm the issue is to pull the glove box and watch the movement a few cycles to visually confirm if the actuator is moving fully, stuttering or acting as if it has the typical broken gear internally.

After that.. then we can dig up the instructions and have you putting a new one in for a reasonable cost.
