ASE Practice Test (B5: Mechanical & Electrical Components) 2

Question 1

When replacing a door hinge on a collision-damaged door, what is the BEST method to ensure proper door alignment?

Accepted Answer

Mark the hinge position on the door and pillar before removal, then replace one hinge at a time

Answer

Marking the original hinge position before removal allows the technician to restore the door to its pre-damage alignment. Replacing one hinge at a time keeps the door supported and in position. Trying to realign a door from scratch after removing all hinges simultaneously takes much longer and may require multiple adjustment attempts to achieve correct gaps and flush alignment.

Question 2

A power window motor runs but the window does not move. What is the MOST likely cause?

Accepted Answer

Broken window regulator or disconnected cable from the motor to the regulator

Answer

If the motor runs (which can be confirmed by listening for motor sound or measuring current draw), the electrical circuit and motor are functional. The failure is mechanical — the regulator arm, cable, or linkage connecting the motor to the window glass has broken or become disconnected. The motor spins but no movement is transferred to the glass. A broken regulator is the most common cause.

Question 3

During door glass removal, what is the purpose of securing the window in the full-up position with masking tape before beginning disassembly?

Accepted Answer

To prevent the glass from dropping down inside the door when the regulator is disconnected

Answer

Before disconnecting the window regulator from the glass, the glass should be secured with tape or a clamp in the up position. When the regulator is unbolted or the cable is released, there is nothing holding the glass, which can suddenly fall inside the door cavity and potentially crack. Taping the glass to the door frame or using a helper prevents this damage.

Question 4

When replacing a windshield using urethane adhesive, how long must the vehicle be kept from being driven (drive-away time)?

Accepted Answer

The minimum drive-away time specified by the urethane manufacturer, typically 30–60 minutes for safe-drive-away urethanes

Answer

The windshield is a structural component in modern vehicles, contributing to roof crush resistance and proper airbag deployment. The urethane adhesive must cure sufficiently to hold the windshield in place during a crash before the vehicle is driven. Safe-drive-away urethanes are formulated to achieve minimum retention strength in 30–60 minutes at room temperature. Driving too soon risks the windshield ejecting in a crash.

Question 5

A technician is replacing a sun/moonroof glass. After installation, the glass does not flush properly with the roof — one edge is higher than the roof panel. What is the FIRST adjustment to make?

Accepted Answer

Adjust the glass height using the glass mounting brackets or adjustment screws in the frame

Answer

Most sunroof/moonroof assemblies have adjustable mounting brackets or bolts that allow the glass to be moved up/down and fore/aft relative to the frame. If one edge sits high, the adjustment bolt or bracket at that corner is turned to lower the glass. Adjusting the glass mounting hardware is always the correct first step before considering seals, shims, or body repairs.
