Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Have you checked all the connectors on the control unit for proper seating?

There is an extensive troubleshooting section in the shop manual, but using a PST-II to read the fault codes is where the procedure begins.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I can use some help. This is my first post to the 996 board. A recent shift from a 928 to a 996. So here is my issue. 1999 996 cab tip with 112,xxx miles has some AC issues. None of my distribution motors are working. Recirc, hot to cold, or dash/panel/floor vents. I have them in a fixed position for cold air for the panel vents (blows very cold air). I checked all relevant fuses, I think. The fan speeds work as well as the AC on/off button. I thought it might be one of the distribution motors but does not make sense that all three would be out. Is there a relay that controls all of these? Any ideas? Thanks!

Unfortunately, the positioning motors are controlled directly from the climatronic HVAC control unit in the dash. There is an extensive troubleshooting section in the shop manual, but using a PST-II to read the fault codes is where the procedure begins. Have you checked all the connectors on the control unit for proper seating?

POST 3 / ORIGINAL POSTEROriginal post

Thanks Doug. Will double check connnections and figure out where to go from there.

POST 4Original post

What about defrost/defog/demist mode..?? In that mode ALL of the system airflow, HOT & DRY (dry compliments of the A/C) should go to the interior windshield surface. HOT airflow even on the hottest August day in Tyronza AR.

This is a source reference. Confirm exact model applicability in the original material.
