Seat Heater Relay?

[Kevin Kingan]

 Im having a problem with my heated seats on my 88 90Q. They work OK but
when I have them on there is a strange clicking noice from under the dash.
It sounds just like a bad relay clicking on and off. My question is this. Is
there some type of Relay that contols the seat heaters? If so where is it
located and what is the part(relay) #? Has anyone had this problem before?
Any help id be very  greatfull for!
Thanks Guys
Kevin
