### Tesla Service's Labor Pricing

The first thing I want to point out is that this is a fairly easy job. I have included enough detail, maybe too much so, that if you can operate a screwdriver, you can probably do this job. However, the juice might not be worth the squeeze. What I mean by that is Tesla has this replacement as a flat rate time (FRT) of [0.54 hours](https://service.tesla.com/docs/Model3/ServiceManual/en-us/GUID-1F4A72C4-BFEB-410B-BB8C-CDEAA02CC36A.html) ≈ 32 minutes. At their [2025 hourly rate of $210/hr](https://www.reddit.com/r/TeslaLounge/comments/1kzers1/high_service_center_hourly_rate/), that is $115 of labor. I think that is a very fair price as it took me about an hour to disassemble and an hour to reassemble. The window assembly is the same price whether you install it yourself or have them install it ([~$165](https://parts.tesla.com/en-US/catalogs/9678bc03-3011-4c95-9620-bb32d391cac0/systemGroups/89377fb9-d068-4510-8ef4-2223c56a3b08?partNumber=1096622-98-L)). However, the one downside of having them install it is you need to schedule an appointment and their availability may be sparse, I’d imagine a week out but it’s not unheard of for it to be multiple weeks. As I rent this car on Turo, I had a trip coming up and needed this fixed ASAP, so I had to take maters into my own hands.

If you’re looking for a quick fix, you might as well try to calibrate the window motors before tearing the door apart. I don’t think I needed to do this after installing the new window motor assembly, seemed like it was calibrated just fine, but it doesn’t hurt and in the spirit of completeness, here’s how.

First, you need to put the car into service mode. To do that, tap on the car in the bottom left, then software, then you need to press and hold on the Model 3 for about five seconds. Then the access code is “service”. Pressing enter will bring us into service mode. There’s a bunch of cool diagnostics in here but... explore it responsibly.

If you tap on service alerts, you can see what your car is unhappy about. My car is unhappy about the rear left window encoder, which makes sense. And apparently it’s been unhappy about that for the last month, but the warnings I guess were never strong enough to be viewable outside of service mode. But, if you see these Window Encoder Stall warnings, you’re probably going to have to replace the assembly.

Going back into service mode, we want to go to closures, then windows. Click on the window that you want to calibrate. For me, the car was waiting on an “unknown” task to complete. I waited a while... it never completed. So I exited service mode then went back in which seemed to fix that. Then, make sure the door is closed. Pinch detection is disabled so keep your grubby little fingers away from the window. And then click run.
