Hello,

Lately my cruise control has been acting up...I will set the cruise at 100km/hr and it'll go up to 120 and then go back down to 100, up to 120, back down to 100. It used to be that it would only do it once and awhile and only when it was cold but now it is doing it all the time. Does anyone know why this is happening? What part do I need to fix this issue. I highway drive one hour each way to work so cruise is definitely necessary!

Thanks in advance!
Tracie
