I changed fuse on 17, it was blown, replaced it. And stuff still doesn't work. Anyone have any other ideas what it could be???

diagnostic shows fuel injection straight line problem. How do you cure this problem?

gear shift was stuck in park; checked brake lights ? Brake lights working.
Attempted to move gear shift into drive
position; Gear shift handle broke off
from steering column; gear shift now
dangling / hanging downwards.

I have went into my brake pedal and look to see if the plug was broken it is not I disassembled it reassembled it and it's still not working also this is the third time which occurred and I need to figure out what the problem is before me and my children are stranded once again

Hi I have a 2004 mercury mountaineer , I need to know if the upper bal joint can be removed without taking the control arm off

The car shut itself off without any warning on an intersection after continuous high revving with a stuck gear. Struggled to start but when it did a loud squealing sound occurred and shut off again. I pressed the fuel reset switch and it started but the engine ran different and would not move at all. After a week a loud knocking/rattling sound occurred after starting and still won't accelerate. (It also did have a transmission problem with gear 2) Could it be that, time chain cassette, worn engine or what?

the rear lights do not turn off
even if i turn the car off and no key in the egnition

my mercury started with a check engine light then went to abs and then brake on dashboard then they would trigger the engine failsafe mode then the abs and brake light would go off we replaced throttle actuator evg valve and abs sensor but now its bringing up the abs and brake lights again with other codes what could be goin on with my car i dont want to spend thousands on stuff thats not wrong

Last shop got it working for four months. Had to get it towed again. Any suggestions
