the winders are cable operated. you must check if the cable and motor are OK if so then the nylon capture assembly is broken. Relocate the cable and tie into the correct position with light gauge galvanized fencing wire. test re grease reinstall there ! If saved 350 dollars!
Some gas gauges read overfull when you fill the gas tank because the needle goes past the full mark on the gauge. A bad sending unit,bad level sender, or stepping motor may be the cause of the gas gauge not working properly.
check the wiering /our your sending unit no good
A faulty thermostat might cause the temp gauge on the 2000 Nissan Altima to raise to hot when the car is not overheating. A faulty thermostat can cause the gauge to move up and down and might even turn the fan on.
