Are you talking about the fan speed that cools the cabin…. It could be the switch, but most likely a blower motor fan control. I believe the resistor that limits voltage to the motor has failed…. my p5 did that as well. I don’t think I fixed it either.So I found that the cooling fan motor is not working properly. Seems to not work on the low speed. I'll need to do some testing this weekend to make sure that it is a fan issue.
Also the new tires are chewing the front inner liners so that's another job I need to look at.

Sucks! Mine got swiped last year in Florida….I started building my own out of a plastic intake from a BMW. Mocked up and tried, adjustments needed. Back to the bench!Lost my cool breeze scoop whike doing 70 on the highway.It was for the NC but I found that it fit the ND. It wasn't as tight as a fit and did make several highway trips in the past, guess I hit that perfect whirl of wind?
 Pulled the car up onto ramps and pulled the plastic panels on the DS off as that is where I thought it fell.  Didn't find it but did find a half a dozen dead cicadas, some leaves and the remnants of a dead bird.  I cleaned it all out, buttoned it back up and stopped my search as I was frustrated and it started to thunder.  Trying to beat the rain, I got the cowl installed along with the new cowl weather stripping (my old one was ripped), tightened the brackets that hold the hard line to the firewall and the wipers installed.  Plan to continue my search for the bolt tomorrow, if I don't find it, I will just order a new one from the dealer.

After seeing some pics online, including the ones you sent, I realized that four of the six that came with the install kit were for the studs on the new plates and the other two were for the firewall studs.
