I will get back to this problem soon, I found a screw that was one of four on the floor. I thought it had dropped down th back of the console and as it is a specially shaped screw, low head with a larger than normal head diameter.I found only four of these screws in my large collection of miscellaneous screws, so I never looked for more.
I can’t let this beat me, although it has done a good job up to now. This is the only thing on the cat that does not work except for the TPMS.
