Having problems with your Mercury Cougar ?
I am having a problem with my brake lights coming on. I can turn on the lights and the turm signals work. I have replaced the brake switch twice with new ones. I also replace the plug that plugs into the brake switch. I have checked the fuses and they are okay. What else can I check that might becausing this problem?
If you have changed the brake lamp switch and it has made absolutely no difference on each occasion I would be checking the earthing connection to the rear lamp clusters.
