Buying a used car is a smart way to save money, but it also comes with hidden risks. While many buyers focus on engine and body condition, they often forget to check the small but important features like ORVMs, power windows, sunroof, and seat controls. These features may seem minor, but they are key to comfort, safety, and resale value.

A proper pre-delivery inspection of used car should include a detailed check of these electrical and mechanical systems. This article explains how to confirm the working condition of ORVMs, power windows, sunroof, and seat controls in a used car.

Why These Features Must Be Checked During Pre-Delivery Inspection

Modern cars come with many convenience features that may stop working over time due to wear and tear, water damage, or electrical issues. These issues are often not visible during a short test drive. A pre-delivery inspection ensures that these systems are checked carefully before purchase.

Importance of Checking These Features

Safety: ORVMs help in lane changing and parking
Comfort: Power windows and seat controls improve driving experience
Resale value: Non-working features reduce resale price
Repair cost: Electrical repairs can be expensive

This is why the importance of pre-delivery inspection becomes even more clear when dealing with used cars.

How to Confirm the Working of ORVMs (Outside Rear View Mirrors)

ORVMs are important for safe driving, especially in city traffic and highways.

What to Check in ORVMs?

Manual or power adjustment: Test both left and right mirrors
Auto folding feature: Check if mirrors fold and open smoothly
Heated mirrors: Verify heating function in cold mode if available
Mirror glass condition: Look for cracks, scratches, or fogging
Mirror alignment: Ensure it aligns properly with your view

How to Test ORVMs?

Turn the ignition on
Use the mirror adjustment switch
Check movement in all directions
Test auto folding by locking and unlocking the car
Check the heating function if available

If the ORVM does not move smoothly or makes noise, it could be a motor issue or a wiring problem.

How to Confirm the Working of Power Windows

Power windows are often ignored but they are a common failure point in used cars.

What to Check

All windows should move smoothly
No unusual noise or jerking
Auto up and down function
Window lock switch works properly
No glass misalignment

How to Test Power Windows

Test each window individually
Press and hold the auto down and auto up function
Check if the window stops at the correct position
Listen for motor noise or grinding sound
Ensure the window closes completely without gaps

If a window moves slowly or gets stuck, it may need motor replacement or wiring repair.

How to Confirm the Working of Sunroof

A sunroof is a premium feature, but it is often the first to fail in used cars due to water leakage or motor issues.

What to Check in a Sunroof?

Smooth opening and closing
No unusual noise from motor
Sunroof alignment and sealing
No water leaks or rust marks
Drain pipes are not blocked

How to Test the Sunroof?

Open and close the sunroof multiple times
Listen for noise or stalling
Check for smooth movement without jerks
Inspect the rubber seal for cracks
Pour a small amount of water around the edges to check for leaks

If water enters the cabin, the sunroof seal or drain pipes may be damaged.

How to Confirm the Working of Seat Controls

Seat controls are important for driver comfort and correct seating posture.

What to Check in Seat Controls?

Manual or electric seat adjustment
Seat forward and backward movement
Seat height adjustment
Backrest angle control
Memory seat function if available
Seat heating or cooling function

How to Test Seat Controls?

Adjust the seat in all directions
Check for smooth movement and no sudden stops
Listen for motor noise or grinding
Ensure the seat locks into place firmly
Test seat heating and cooling if available

Faulty seat motors or broken tracks can be expensive to repair, so it is important to check them during inspection.

Quick Feature Check Table

Feature	What to Test	Common Problems
ORVMs	Adjustment, folding, heating	Motor failure, broken mirror
Power Windows	Smooth up and down	Motor issues, wiring faults
Sunroof	Opening, sealing, leaks	Water leak, motor failure

Why a pre-delivery inspection Matters for These Features

A pre-delivery inspection of a used car helps detect hidden electrical or mechanical issues early. These problems are often expensive to repair after purchase. Checking ORVMs, power windows, sunroof, and seat controls ensures you get a car that is fully functional and safe.
