Has anyone repaired cooling louvers?

[LonelyMS]

@ResHacker how come you did not subscribe for the toolbox3 option via Tesla service page? As it does not require SW downgrading, removing the instrument panel, etc... and its cheap for 1h?

Toolbox 2.1 installation was +- for the same money as 1h TB3 subscription. I also wanted some permanent diag solution, not just for 1h. Yeah, it can happen, something will not be possible to solve with TB2, then I pay the 1h TB3 for sure. I also like to tinker and learn something new with my car, so don't mind to put the IC disp out. But in this particular case I needed the IC out anyway to try to get rid of the bubbles. I have also connected the LAN cables in the way I no more need to put IC out in the future and can easily diag it whenever I want. Downgrade of the SW to .5 is no big deal as it's a version from +-Aug 2022, so still v11 with all the features available in .12 SW.

I have no error codes /messages. I think it’s just strange….They sent a repair estimate without seeing the car and all the louvers work properly. I’m pretty sure I’m just gonna cancel my appointment and have a tech add some refrigerant.

Bumping this up
……. 2017 Tesla P100D
My car blows ice cold for 30-45 mins and then out of nowhere it feels like the AC is off even though it’s still blowing ( feels like fan air only ) then after a few mins will blow cool again ……..,
Remote diagnosis from Tesla replace front left and right louvre.
Funny thing is they are both working L and R . I can see them opening and closing at different times.

Does this seem correct ? Car goes in Aug 12
Cost estimate $989
My take I think it’s just low on coolant
No error codes……
Thx in advance e on any help

I think their blowing smoke up your a$$.

I would tend to agree with this as well.

removed the front bumper for facelift conversion and was greeted by the carnage in the pictures. Seems my condensers and rad are on their way out…
Replaced the reinforcement as well as was far from being safe after 8 canadian winters.
Will try later both chinese actuators to see if they are working properly.

 

[kirkusss]

I don’t understand the louvers anymore… have installed the new bumper, new louvers and the 2 actuators from Aliexpress.
Now during the test the right side opens and closes, nothing on the left and the test reports the other way around…left ok, right not ok…
What is the cheapest way to get Toolbox 3 access?

Afaik your options are:

1. Go to 3rd party repair shop
2. Signup on service.tesla.com - 1 day rental for toolbox is $230CAD/day up here (and you'll need the cable to connect your laptop to your car as well)

Sorry for of topic question but you did not had any issues with the map data and downgraded SW?

 

[ResHacker]

No issues with map data....or at least no new issues Some of the map data still doesn't match the changes even after few months after but that's not related to the downgrade Maybe map data and SW itself are separated as both are upgrading independently.

@kirkusss Thanks for the photos, quite shocked how much rust is there and how much are the condensers eaten probably by salt... Wondering how does my car under the bonnet look like..

 

[LonelyMS]

Fyi, there is also 1H option for toolbox, should be plenty for the calibrations? Cable is around 20$ from ali.

 

[KalJoMoS]

I was surprised as well, as much as I have peaked under there I have not seen that level of corrosion! Although we have quite heavy salt treatment on our roads during winter, which is almost six months in a year.

Yep, should be pretty enough If you buy just the Facra connector, then it's much cheaper. Like 2$ only..

 

[kirkusss]

Probably need to register for US or another region, Canada only has daily as a minimum.
Have some fakra connectors from my BMW retrofit days.
For the corrosion removing the nose cone should reveal the crash assembly for inspection.
But yes, everything is eaten in my front end. Parts are not that expensive, but labor probably is to replace the condensers and center rad.

Are the connectors the same for both MCU1 and MCU2?

Connectors should be the same but I'm not sure how about MCU2 and this diag...not shure whether it's possible.

Had the AC and fan stop working on a 2013 MS 60. Tesla service ordered a new center louvre and a new blower. When they opened it up they discovered a frayed wire, and left the new center louvre part in the back seat. I told Tesla I had it, and they said I could bring it in or "dispose" of it - my choice. It's brand new OEM: Tesla Model S (2012-17) Center Louver Assembly NEW OEM Part#1007256-00-K | eBay

 

[kirkusss]

It seems louvers are always powered when the car is on and they cannot br manually opened or closed. With the car powered off they can be moved in the open position and as soon as the car starts they close.

 

[LonelyMS]

I am really keen to see the results of the calibration via the toolboox3. Do you plan it?

Have you tried different combinations now of your existing and replacement actuators? Wonder if you can find a pair that plays nicely together….
