Steering wheel heating not working

[roadsalt]

Hey @roadsalt, awesome that you finally solved your wheel!
I'm still chasing my issue, essentially the same problem, good fuse, everything seems right but no switch light, no heat. I saw this new discovery of yours and pulled my steering column apart right away! No luck on that 4 pin connector, all the wires are good. I'm wondering about the switch you purchased. Did you do any continuity testing between this 4 pin connector in the column and the switch?
Thanks!

Thank you. I'm sorry it didn't help with yours! I bought two components that ultimately were not the issue.
1- the multifunction cluster with the physical heated steering button. I don't have an iron clad patron for it
2- then there was the heated steering wheel control switch in the wheel itself. Took 10 minutes to replace. Lexus 55910-50010 I got it for $65

I gave up on continuity testing after the millionth try. It was driving me crazy. I was lucky to find this pulled wire.
