For the last 15yrs I have owned and driven daily a '99 4.6 HSE. I have replaced and repaired many parts over years but it is generally in pretty good shape. 225k on clock and still going strong.
Lately my cruise control dies after about 10 - 20 mins on road. Once it dies it won't start again while driving; and won't work again on day. I've arrived at destinations and left for up to 2 -3 hrs before starting out again. But unlike when first starting, the CC won't turn on at all.
It seems like when the engine heats up to normal running temp the CC won't work. My regular mechanic and an auto elec can find nothing wrong with the system itself. My mechanic suggests it may be a 'dry' solder joint on control panel; which loses connection when engine heats up.
I've looked through many many posts but haven't seen anything specifically related.
Anybody got any ideas?? The idea of locating a 'dry' solder joint on control panel doesn't sound feasible??
P.S. On rough surfaces it has more rattles in it than a babies creche. Is this normal for an old P38A? Can rattles be fixed by removing interior panels and reinstalling with better seals and fixings?
