06 KW w900 weird problem , Jake and cruise control

I wonder if anyone else has hade this problem? This just started this winter. When the temp. is below about 45 degrees outside , my cruise control and Jake brake don't work correctly . The cruise cuts off , and the jake is intermittent . Seems to go away when it warms up outside.
I replaced the Throttle Position Sensor , and the on/off switch for the cruise control , no difference .
Truly puzzled !

 

Try to keep that area cleaned out , but I'll check it again.

 

That's what I thought. When I described what it was doing , KW parts man shook his head , said it Was probably the accelerator position sensor. Turned out it wasn't . I'll get the clutch pedal switch tomorrow , I guess . I've already Looked at it , it's not loose.

 

no. It comes on , stops , then starts again. The cruise cuts out , usually when there's no load on the engine , like coming down a small rise , but not coming down fast enough for the Jake to come on. Then after a second or two , the Jake kicks in , like you've touched the brake.
