Question 1

A 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?

TheoryPractice · Accepted 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.

Question 2

What must be done before removing an electrically heated rear window?

TheoryPractice · Accepted 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.

Question 3

When 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?

TheoryPractice · Accepted 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.

Question 4

A vehicle's power window operates slowly and makes a grinding noise when closing. The most likely cause is:

TheoryPractice · Accepted 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.

Question 5

During windshield replacement, what is the purpose of applying primer to the pinchweld?

TheoryPractice · Accepted 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.

Question 6

After replacing a windshield with ADAS features, what should be performed before returning the vehicle to the customer?

TheoryPractice · Accepted 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.

Question 7

A 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?

TheoryPractice · Accepted 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.

Question 8

A customer complains of wind noise around the driver's door at highway speeds. The LEAST likely cause would be:

TheoryPractice · Accepted 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.

Question 9

When replacing stationary quarter glass, what is the correct sequence for installation?

TheoryPractice · Accepted 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.

Question 10

What should be checked when diagnosing a power window that will not operate in either direction?

TheoryPractice · Accepted 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.
