Read evidence and context

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.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

so since I picked up my car I have always had excellent AC...but never any heat, and any vent position always blows air out of footwell, windshield and dashboard vents (doesnt matter what is selected). Car is an �00 cabrio. I recently picked up a durametric and am getting four errors: 26 - mixing flap motor fault 27 - central flap motor fault 28 - footwell defr. flaps motor fault 29 - outs./recirc. air fl. mot. fault so seems strange that all those motors would be burned out...have been searching but hoping someone can point me to some good troubleshooting steps? thank you in advance!

POST 2Original post

Start with the fuses. If you don’t have a list of them PM me your email and I can shoot you the full wiring diagram which includes them. From there, if nobody chimes in that’s done it, the workshop manuals and google will be your best friend.

POST 3 / ORIGINAL POSTEROriginal post

Thank you...I did indeed check fuses in the box. I only saw two listed for the system (is that correct). Both checked out fine and I swapped with new just in case there was a break I couldn’t see.

POST 4Original post

I'm going to make a wild guess. Pull the HVAC panel from the dash and make sure all the wires are connected in back. Seems like that is central to everything else working properly, i.e., all the motors are controlled from that unit.

POST 5 / ORIGINAL POSTEROriginal post

Pulled the CCU...everything was plugged in (4 plugs) across back...cleaned contacts and replugged...still same. Wonder if I can find a known good unit locally to try and plug in to rule out the CCU...
