Hi I am not too good at reading electrical diagrams but it seems that I have 2 intermittent electrical faults that occur together that may have a common junction. Does anyone know if the steering column speaker and the seat heaters have a common electrical connection point?
thanks

 

Does the tell-tale lamp in the seat heater switch(es) still function when the fault occurs?

 

yes just no heat in the seat

 

FWIW, both the steering column tilt and seat control modules are independent problem areas in our cars. The tilt function works in short bursts instead of a smooth movement, and the seat controls sometimes stop working and/or fail to heat. Both problems are well documented on this forum and have, in most cases, somewhat inexpensive fixes.
