04 Navigator PCM, and AC issues.
I have a 04 Lincoln Navigator and have a few issues, any help would be great.
1st. Cruise not working and have narrowed it down to PCM, Do you think i can just have PCM flashed and it should fix it, or do i need a whole new one, and where do i get it besides dealer who wants $700 for it plus $100 to flash it. The only thing not working is the Cruise
2nd. AC blows cold but not cold enough especially when really hot out. i have check the freon and its full, any ideas, its cold, but not near like it should be. so i know its coming on.
3rd. I get the rattles when i first start the truck, especially after it has been sitting for a little while. getting worse as the temp is getting hotter? i have heard it could be valves, or timing chain, should i do anything to it, or just let it go.
thanks for the help.
