Upon closer inspection, the headlights are definitely not hazy, just have the diffuser lenses. I never heard of that before. Oh well. On another note, I decided to use the new TPMS sensors I bought for the new wheels I have waiting to go on the Silverado in order to get the message on the Tahoe's DIC to go away. (Just temporary until I need them for the new wheels, at which time I plan on pulling the old ones out of the old wheels and swapping them.) I hate warning messages. So I built a pipe bomb out of PVC pipe and put them inside and pressurized it. I tried to get them to get recognized by the Tahoe but increasing/decreasing the pressure didn't do it. I looked online, wondering if they needed to be activated, and found out they are stored in "off" mode and they needed to be activated. So I bought a tool to activate them. Still no luck, and then tonight I realized I'd bought an alldatadiy subscription for the truck when I was trying to diagnose the airbag issue. (That's another issue I've been working on.) So I checked the procedure for replacing a TPMS sensor and of course it isn't so easy:
"Important: A service replacement tire pressure sensor is shipped in OFF mode. In this mode the sensor unique identification code cannot be learned into the remote control door lock receiver (RCDLR) memory. The sensor must be taken out of OFF mode by spinning the tire/wheel assembly above 32 km/h (20 mph) in order to close the sensors internal roll
switch for at least 10 seconds."
So now I'm trying to think of a way to spin them at 20 mph while they're in the pipe bomb.... any ideas? I could always cut the end cap off it, remove them, spin them somehow, and put a new end cap on...
