What You're Actually Buying
This is the full driver-side (LH) door mirror head for Volvo VNL trucks, 2018 through 2024 model years - heated glass, electric remote adjust, the whole assembly that bolts to the mirror arm. Not just a glass replacement, the complete housing and motor unit.
VNL mirror setups changed enough over the 2018 refresh that older VN/VNL mirrors won't just swap over - arm mounting and wiring harness plug are different. This one's built for the current-generation VNL cab, so if your truck's an '18 or newer, this is the family it falls in.
Heated element helps in the winter runs up here in the Northwest, and the electric adjust means it's wired into the cab controls - no manual knob on this one. Confirm your truck actually has power mirrors before ordering, some spec sheets came through with manual arms on lower trim work trucks.
Why All These Numbers Cross
82239803 is the Volvo part number, 20798620 is the number that shows up as the OEM/mfr reference on most catalogs and cross-ref software - these two point at the same mirror assembly, just different number sets depending on which parts system you're pulling from.
The other numbers in the table - VL-0306-L, 20520346, WA128-0201, UPI41320, 564.43005, 85134000 - are aftermarket suppliers and alternate catalog listings that build to the same mirror spec: same mounting pattern, same electrical connector, same glass heater wiring. 20798619 shows up as a cross-reference too, sometimes used interchangeably depending on running production changes Volvo made mid-cycle.
Where guys get burned on mirrors isn't the mounting bolts, it's the wiring plug pin-out and the arm attachment point. Volvo tweaked connector pin counts a couple times through this VNL generation. Numbers crossing on paper doesn't mean the plug lines up on your truck - pull the old mirror and check the connector before you order, or better yet, give us your VIN and we'll confirm against the build sheet.
Ordering From PartStop
We're stocked out of Tacoma and this one's usually a same-day pull if you're local - walk in, we bolt-check it against your old unit before you leave the counter. Not everybody's got that luxury, so we ship nationwide too, most orders out same business day.
This is aftermarket, not a Volvo-branded mirror, and we don't tell you it's a guaranteed fit sight unseen - that's on you or your VIN to confirm, same as we'd tell any fleet mechanic walking in. But the assembly matches Volvo's mounting and wiring for this generation VNL.
Backed by our standard 6+ month warranty. If it doesn't match up once you've got it in hand, call us before you start cutting wires or drilling anything - we'll sort the return or find you the right number.

Frequently asked questions
Does 20798620 fit my 2022 VNL 300?
Should, if it's got the heated electric mirror setup from the factory - that's the number range Volvo uses for this generation. Surest way to know for sure is give us the VIN or pull the number off your old mirror housing, we'll cross it before you buy.
Is this the same as the WA128-0201 mirror?
WA128-0201 is one of the aftermarket cross-references that builds to the same mirror spec - same mount, same wiring. It's not a Volvo part number, it's a different manufacturer's catalog listing for what's essentially the same assembly. We stock this listing under the 20798620/82239803 reference.
My mirror doesn't have heat, will this one still work?
It'll bolt on fine but you'd be wiring in a heated mirror on a harness that might not have that circuit run. Check your dash switch - if there's no mirror heat button, your truck likely wasn't wired for it and you'd want the non-heated version instead.
