1996 850 Sedan.

My ABS light has come on. It initially was not an issue with me.

I park my vehicle in the HEAT, start my vehicle in the heat,
Indicators and Speedomoter do not work.
I will drive the car for some time and all will work again after
re-start.
I was told that it is linked to the ABS snesor and that latter needs
to be replaced even jeopardizing a short in and ultimate destruction
of the wirng-harnass.

A few days ago I start the 850 sedan and NO LIGHTS.
Vehicle was parked in low 90 degree weather
I brake and the the warning lights to my seatbelt warning indicators
flash.
I was told it is my ignition and that makes sense as in recent months
I continually had to use that button  in order to palce my vehicle in
drive.

Do I have 1 problem and only need to change the IGNITION or do I have
2 Problems and also have the ABS unit changed and replaced.
They scared me when they said that the potential of damage to the
wiring harnass is an outcome.

I am open to your opnions.
