My 1999 cougar has issues.All lights,dash lights,headlights pulse dim to bright. After driving the car it sometimes will not turn over, it is not even getting power to the starter solenoid when it does this. This problem seems to resolve itself after 15 to 20 minutes, although sometimes will not turn over for days. This problem also causes the motor to surge slightly. Obviously its electrical,but there are no repair manuals available for this vehicle, has anyone else experienced a problem like t

It is not affected by the dash light dimmer control switch, but does changed it's luminance when the headlights or parking lights are turned on of off. At first I thought it was a heat/cold problem but now it is more random, with it being dim and now off most of the time. Any suggestions on how to make it stay bright and readable?
