Hey everyone, first of all long time no speak.. Good to see the place still kicking along nice and strong

So my cruise control has stopped working. Anyway here goes, ill try to include everything..

2001 liberty AWD (heritage not that its important)

I had been having CEL's showing up for the first 30 seconds or so after starting the engine about 80% of the time for about 2 years now but out of nowhere the CEL's pretty much vanished and are probably once every 15 or 20 starts for a few seconds at best.

At the same time the CEL's went missing so did the flash of all the indicators when I hit my central locking button on the key, otherwise completely functional. This is with the factory central locking system with one of the cars original keys if that matters. Im assuming this is related which is why Ive included it..

And last but not least the cruise control isn't working, the cruise light still goes on and off when i toggle the cruise control button on the dash and the click noise still happens behind the glove box/under the dash whenever i press the button(from the main fuse relay i would assume).

Ive checked the ABS/Cruise and central locking fuses and they are all OK

My next point of call would be the O2 sensor but my past experience suggests I would have a CEL if the sensor isn't functional.

So yeah im no expert and I would like to be more confident before I change out the O2 sensor.

Your thoughts would be appreciated
