Q1A vehicle has a small crack at the edge of the windshield. Technician A says this crack can be repaired with a special resin. Technician B says any crack in the driver's primary viewing area should result in windshield replacement. Who is right?
Show answer
✓ Correct answer: Both A and B
A crack at the edge of the windshield (outside the primary viewing area) can often be repaired with a special resin. However, cracks in the driver's primary viewing area typically require windshield replacement for safety reasons.
Q2What must be done before removing an electrically heated rear window?
Show answer
✓ Correct answer: Disconnect the electrical connections
Disconnecting electrical connections is essential before removing a heated rear window to prevent damage to the electrical heating elements and wiring.
Q3When installing a new door window, technician A says to check for proper window track alignment. Technician B says to adjust the window stop to prevent the window from going too high. Who is right?
Show answer
✓ Correct answer: Both A and B
Both technicians are correct. Window track alignment ensures smooth operation, while proper adjustment of window stops prevents the window from being raised too high, which could damage the glass or mechanism.
Q4A vehicle's power window operates slowly and makes a grinding noise when closing. The most likely cause is:
Show answer
✓ Correct answer: Damaged window regulator
A damaged regulator is the most likely cause of a window that operates slowly and makes grinding noises, as the mechanical components that raise and lower the glass are worn or damaged.
Q5During windshield replacement, what is the purpose of applying primer to the pinchweld?
Show answer
✓ Correct answer: To promote adhesion and provide UV protection
Primer is applied to the pinchweld to promote adhesion between the urethane adhesive and the vehicle body, and to provide UV protection to prevent degradation of the adhesive bond.
Q6After replacing a windshield with ADAS features, what should be performed before returning the vehicle to the customer?
Show answer
✓ Correct answer: ADAS system calibration
After replacing a windshield with ADAS (Advanced Driver Assistance Systems) features, system calibration must be performed to ensure proper operation of safety systems like forward collision warning or lane departure warning.
Q7A customer complains of water leaking into the vehicle after a windshield replacement. Technician A says to check the urethane seal. Technician B says to check the cowl panel installation. Who is right?
Show answer
✓ Correct answer: Both A and B
Both locations could be sources of water leaks. The urethane seal around the windshield and improper cowl panel installation are common causes of water intrusion after windshield replacement.
Q8A customer complains of wind noise around the driver's door at highway speeds. The LEAST likely cause would be:
Show answer
✓ Correct answer: Damaged door latch
A damaged door latch would typically cause issues with door operation and security, but would not be a primary cause of wind noise, which is more commonly related to weather stripping, window alignment, or door fit.
Q9When replacing stationary quarter glass, what is the correct sequence for installation?
Show answer
✓ Correct answer: Clean pinchweld, apply primer, apply urethane, install glass
The proper sequence is to clean and prepare the pinchweld, apply primer, apply urethane adhesive, then position and secure the glass. This ensures proper adhesion and prevents leaks.
Q10What should be checked when diagnosing a power window that will not operate in either direction?
Show answer
✓ Correct answer: Window fuse
When a power window fails to operate in either direction, checking the fuse is the logical first step before investigating other components like the switch, motor, or wiring.
