2004 Lincoln Aviator ProblemsCheck Engine Light Due to a PCV System Vacuum Leak
A vacuum leak from the PCV grommet vacuum leak can cause the Check Engine Light to illuminate. The molded rubber hose connections may crack and collapse, causing the vehicle to run roughly. A damaged PCV hose will require replacement.
You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 15,000 to 30,000 miles. If the fluid is dark or burned then the transmission fluid should be changed.
An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.
2004 Lincoln Aviator Questionsmy car turns on but wont start at all batter is good, not sure what else to do? (1 answer)
i checked my battery, the started was hot wired and turn on but wouldnt afterward when key was inserted. im not sure if the relays are bad or the fuses.
I have been losing coolant and running hot pressure tested system and found no leaks any ideas on this
My fuse for the headlights burned and melted into the fuse location. I was told this is a common problem for the Aviator. I want to know if you have to replace the whole box, or can the fuse location just be cleaned and a new fuse entered. And is the dealer the only one that can replace the box?
