Side mirror replacement at Route 66 Auto Repair in Upland covers mirrors clipped in a parking lot, cracked glass, loose housings and power mirrors that stopped moving. Sometimes only the glass needs replacing. Other times the whole assembly does, especially when it carries a turn signal, heater or blind spot sensor. Our ASE-certified technicians check what your mirror has and put the right option on a written estimate.
When does a side mirror need replacing?
- Cracked or missing mirror glass
- A housing knocked off or hanging by its wires
- A mirror that vibrates at speed and blurs the view
- Power adjust that no longer moves the glass
- A dead turn signal or blind spot light in the mirror
- A folding mirror that will not fold or unfold
Glass only, or the whole mirror?
If the housing and motor are fine and only the glass is cracked, replacing the glass on its backing plate is the smaller job. If the housing is broken, the mount is loose or the power motor has failed, a full assembly is usually the better fix.
Features matter. Heated glass, turn signals, puddle lights, memory and blind spot sensors all change which part fits. We check your mirror against your vehicle before ordering, and blind spot warning is tested after install. Mirrors lost in a bigger impact may need a look at the door too; our auto body repair page explains that side.
Our side mirror replacement process
Step 1: Identify the features
We note heat, signal, memory, folding and sensor features on your mirror.
Step 2: Quote the right part
The written estimate lists glass only or full assembly, with the reason.
Step 3: Install and connect
The door panel comes off if needed, the mirror is mounted, and any damaged pigtail gets a proper wiring harness repair.
Step 4: Test every function
Adjust, fold, heat, signal and blind spot functions are each tested.

How pricing and timing work
Glass-only jobs cost less than full assemblies, and mirrors with sensors or cameras cost more. Painted housings may arrive unpainted; we tell you that up front and do not claim to paint-match. Your written estimate covers the part and labor. AAA members get 10% off parts and labor, up to $75. Common mirrors can often be done same day when the board allows. You can also check the NHTSA recall lookup (opens in a new tab) in case your mirror or its wiring has an open recall.
Aftercare after a side mirror replacement
Readjust the mirror from your seat before your first drive, and fold it in when parking in tight spots on busy streets. If it vibrates or a feature stops working, bring it back and it goes to the front of the line. Our rearview mirror repair page covers the inside mirror.


Frequently asked questions
Can you replace just the mirror glass?
Yes, when the housing and motor are fine. The replacement glass comes on a backing plate that clips in. If your glass is heated, we match that so the heater still works.
Is it legal to drive without a side mirror?
Rules vary, and a missing driver mirror is a real safety gap. Treat it as need-now and get it replaced soon. We can often fit a common mirror the same day when the board allows.
Will the new mirror match my paint?
Some replacement housings come pre-painted in common colors, and others arrive in black or primer. We tell you which before ordering. We do not claim a factory paint match.
