Climate Control Display Flashing 9 Times - 2006 C4S Cab

Recommended Posts

Hello - I just noticed that after diagnosing an A/C issue in my car and running a system test on Durametric Pro, my climate control screen (all numbers and graphics) flash 9 times.  The unit is functioning correctly otherwise.  How do I stop the screen from flashing?

Quick follow up in case anyone else experiences this. You have to have the car running when executing the durametric HVAC test sequence. Once I did this, the flashing went away.

The Durametric is a great tool, but also dangerous! You have to think before pushing the button "what will this actually do?"  Well done for finding it though!

My vehicle is doing this, but then blows the climate control fuse midway when trying to run the system test on the durametric. Any thoughts?

Sounds like something is legitimately failing and drawing high current to blow the fuse.  What other errors are coming up?
