Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
Do the brake lights work? Thanks.
This usually means the shifter assembly needs to be replaced which contains the shift interlock solenoid. At the solenoid, check the wires as follows: Black wire is a ground. There will be battery voltage on the Yellow/Brown wire with the key on. The Purple wire will get 12 volts when stepping on the brake to release the solenoid. If all the wires test OK, replace the solenoid which at this time is serviced as part of the shifter assembly. Let me know how it goes or if you have more questions, thanks.
I basic tool set should work fine. Do you have column shifter or center console shifter? I can give replacement instructions.
Here are replacement instructions, let me know if you have questions. Thanks.
You will need a multimeter which you can buy from parts store for about $15. Let me know if you have more questions, thanks.
