Re: P0750 code for 04 Jeep Laredo
The problem with a broken wire in the drivers door rubber boot is something what happens more often. Normally the windows donīt work, the driver door doesnīt lock/unlock and the interior lights stay on. This problem should not have to do anything with the check engine light or the P0740 DTC. Next time when your check engine light comes on, you can safe you the trip to any garage and check the fault code yourself. You just switch the ignition switch on/off for 3 consecutive times and leave it in on after the third time. The odometer will show DONE when no faults, or any fault code.
Regarding the noise outside, any abnormal noise which was not there before? What does it sound like and from which position? Can you hear it inside the car when driving?
