my truck has an on-star speaker above the driver seat but the truck itself doesn't have onstar. the problem is that the speaker keeps making a buzz or poping kind of sound, hard to describe. sort of like turning on a blower motor in an old truck. has anyone else run into this problem?:banghead:

Its not a speaker it is a sensor for the climate control. It is dirty and needs to be cleaned.

That is not an on-star component, but rather it is a Temp sensor (with fan)for the climate control.
