Quick answer: Match driver or passenger side, power or manual adjustment, heated-glass capability if equipped, connector shape and pin count, mounting pattern, housing style, and finish. Compare photos of the plug and mounting base—not only the front of the mirror.
Start with the exact mirror and vehicle
Record the vehicle as a 2008 Scion tC and confirm the body style and original equipment on the car. Then inspect the mirror being replaced. Determine whether you need the complete assembly, only the glass, an actuator, the painted cap, or another component. Ordering a complete assembly when only glass is damaged may add cost; ordering glass alone will not repair a cracked base or failed motor.
Note which side is needed from the driver’s point of view. Listings sometimes use left/right, LH/RH, or driver/passenger. Save the VIN for catalog checks, but still compare the installed mirror because collision repairs and previous replacements can change what is present.
Compare the fitment details
- Driver-side or passenger-side position
- Complete assembly, replacement glass, housing, cap, or motor
- Power adjustment versus manual adjustment
- Heated or non-heated glass and any indicator or specialty feature
- Electrical connector shape, latch location, pin count, and wire count
- Mounting studs or bolts, spacing, base outline, gasket, and interior trim interface
- Fold type and range of motion
- Painted, textured black, primed, or paint-to-match finish
- Glass shape, curvature, markings, and viewing field
Remove the interior sail-panel trim only when it can be done safely and without damaging clips. Photograph the electrical connector before disconnecting it. A seller photo of the connector is valuable evidence; a phrase such as “power mirror” may not tell you whether every feature or pin matches.
Search for the part you actually need
A useful first query is 2008 Scion tC side mirror. Add the side and feature set, such as “driver power mirror connector” or “passenger mirror glass.” If the old assembly has a molded, manufacturer, or interchange number, search that number separately and confirm what it identifies. Do not assume every number printed on the plastic is the retail assembly number.
Review the full application list and exclusions. Compare listing photos of the mounting base, connector, glass, and rear housing with your photos. For a used mirror, ask whether the adjustment motor, folding joint, heater, connector latch, studs, and glass are intact. For an aftermarket assembly, check whether the cap must be painted and whether the glass shape or vibration performance differs from the original.
Before buying and after arrival
Confirm the return policy before painting or installing the mirror, because paint work may make it nonreturnable. Include shipping cost and possible paint materials when comparing price. If the mirror was damaged in a collision, inspect the door mounting area, wiring, and interior trim for related damage before assuming a new assembly will sit correctly.
When the part arrives, compare the base, studs, gasket, connector, pin layout, wiring length, and travel before removing protective films or painting. Temporarily connect electrical features only when the service procedure allows it. Verify adjustment direction and heating operation if equipped, then install to the manufacturer’s fastening guidance without overtightening the door or mirror base.
