I have a 1972 Mercury Cougar XR7 Convertible. I have an issue with the rear Passenger signal light that wont turn on. I changed all the fuses and the inside blinker light now works. However the taillight is still not working. The signal light on the right side does work.
The 2nd issue is the Driver side Brake light wont turn on however the Passenger side Brake light does work. I put a new sequential unit and the problem continued. I am going to check the wires for a loose connection by removing the taillight a unit and the bumper.
Any suggestions
First I’d use the trouble shooting guide that Vic Yarberry has on his website. This sounds like a bad turn signal switch to me.
