The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.
The headlight switch used on the GMC Yukon Denali is known to fail through normal operation. Since the headlight switch is also integrated into the interior lights, a malfunctioning switch can cause issues with interior lights as well.
- Symptoms of a failed headlight switch include:
- Headlights and taillights failing to turn on or off
- Interior lights flicker, or fail to turn on or off
- Gauge cluster lighting off or flickering with headlights on
- Parking light malfunctions
This issue is well known with General Motors Trucks and SUVs, and is solved by testing and, if needed, replacing the headlight/dimmer switch. Bad grounding wires at the tail-lights, and dirty/corroded tow package wires can also lead to some of these issues.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
The sunroof may stop working for various different reasons. Our technicians tell us it is often better to replace the complete sunroof assembly than to try and repair the old one.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
A clicking noise may be noted from the turn signal flasher after the turn signals are switched off. This is commonly cause by a faulty turn signal switch which will require replacement.
The fuel pump may fail causing the engine to stall and not restart.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
The rear window defogger may stop working due to a wire terminal broken off of the rear glass. Our technicians tell us that terminal can be reattached using a special glue or silver solder.
