It happened half way through a long trip, we stopped to get some drinks and kept on our way, and after hitting a 110 zone, I put the cruise control on, and it dropped speed so slowly I didn't notice. It doesn't disengage, just doesn't hold.
On top of that, the aircon also doesn't seem to engage correctly anymore either. I can hear the compressor cycling on and off rather rapidly. It was regassed when I bought it as the compressor didn't engage, so I assumed a leak, but was told it wasn't leaking, just the control unit was bad, so I soldered the circuit to repair it.
I'm aware they're two seperate circuits, but what's the likelyhood of both these starting to fail together? Where should I start looking?
