Hi everyone!

So, I pulled out the cabin air filter in the glove box, cleaned it and put it back in, and now when I start the car the ventilation system acts confused.

Initially nothing happens, the lights for Auto, etc, do not come on as they did before. Eventually after a minute or so sometimes the AC starts up and other times i have
to go Climate and turn it on manually. At that point everything works normally although now the interior is set for 75 degrees versus it was 70 before I removed the filter.

I am guessing some delicate sensor has been disturbed despite my best effort to carefully refit the black plastic cover plate, I did not bother fitting the "shelf" plate.

Could not fitting the shelf plate have disturbed things? I really do not want the cost and hassle of taking it to a dealer, can someone comment on this?

 

It's on the FAQ on here:

Post #3 and #12 on what to do before doing the cabin filter change.

 

When I changed mine the filter wasn't quite seated in the holder correctly. I fixed it and it worked fine after. ALWAYS PUT THE SYSTEM ON RECIRCULATE PRIOR TO ACCESSING SO THE DOOR IS OPEN.
