No Crank, No Start Electrical Issue 2006 STS-V

[@rstelzer2928]

Had the same problem on my 2006 STS V6. Hard to believe, but the problem traced to a bad passenger side window switch. Crack open the window during rain and it runs right to the window switch, and poof; you now have a serious electrical GHOST running around your entire electrical system. You cannot just change out the switch panel for the buttons, you also have to reprogram it as a new install. Once "installed" everything works fine. I also ordered some of those add-on rain shields for all 4 windows!!! If you prefer to; go ahead and do the standard "replace all suspected modules and switches" in the trunk, under hood, transmission, electronics in shift system, etc... (see following suggestions in comments) including the start button first; if you like to spend money for nothing. I did. The new switch was $100. The cost to trace it out was $100. Spent $1,000 before the $200 fix. Mechanics don't refund labor or parts cost just because it didn't fix the problem. Suggest find a great electrical mechanic and keep him happy, rather than use a parts changer mechanic. Worth his weight in GOLD!

Check the the starter relay fuse that happen to me before I have 06 sts v6

[@headhancho6406]

Did you ever figure it out it could be the Neutral safety switch because it’s not showing you the P on the cluster

Common problem, search for the shift to park message on the Cadillac forums. There is a switch that goes bad. I saw the other fuse block video

[@josephburks5350]

Yes... it's a very common issue. The switch is $37 and about 4 hours of labor to fix and a day to reinstall the shifter. I am in the process of fixing a 2008 STS I picked up with the same issue

[@missincredible6087]

I have a shift to park message on my Cadillac 06 sts

[@whoisfluffy3476]

Bad neutral safety switch and no comm with Ecu. As shown by no CEL.

[@rstelzer2928]

Isn't that inside the transmission?

[@MrFixIt.]

I have that now

[@Ictbreadwinner]

I figured it out

[@thenewone712]

You did

[@jimmy5629]

Shift linkage is bad

[@ic1815]

Lol. This is the micro switches in the gear shifter. Extremely common problem. Not an “electrical issue”. It’s a common fault that’s easily fixed.

[@ddt1983]

Please tell me how to fix this

[@dudedude7440]

How do you fix it

[@headhancho6406]

Same thing happened to my V it was a faulty module in the trunk
