cruise getting recalcitrant...

[B@fink]

After leaving the 8 for a few days whilst working away i was soooooooooooo pleased to get back in after the diseasel hire car but disaster! the cruise wouldn't kick in, nada, nothing. Drove it home, left it over night and on the way back to work next morning, worked first time of asking!? But a few miles further on i tried it again and it was dead again, no response to the switch. The switch shouldn't be icky as i use cruise quite often and its never missed a beat up to now. Its a PF D2, the vac pipes look like they are where they should be, sooooo what are the next bits to peek at? Not had time for a proper nosey and just trying to short cut the checks
