I am looking at these guys when I need mine repaired. They are the only ones I have found that will repair the faded display on my auto climate control. Looks like they repair yours too.
I haven't used them yet so I can't say from experience, but it looks like they stand behind their work.

They are the only ones I have found that will repair the faded display on my auto climate control.

King, did they say they would repair the faded display on the automatic climate control? I looked at their warranty and it specifically excludes the display on the auto control without nav.

 

Can anyone confirm for sure that 84010-48270 will work

DC, I looked at Olathe for fitment because I was curious, and 84010-48270 did not come up on any genuine Toyota site as a legitimate replacement part number.
I know from previous experience that many, if not all, of the manufacturing line part numbers are different from the replacement part numbers you would get from the dealer. It looks like 84010-48270 is the manufacturing line part number marked on an OE part.
If you remove your panel, you may find the same 84010-48270 part number.
But are you buying a used part that might have the same problem?

My part # is 84010-48180. I suppose I will order 84010-48270 and see if it works. My understanding is that the temperature control issue is more prevalent in the 04-05 Highlanders, so this updated part hopefully wouldn't have the same issue.

 

Never had any issues with that part of the car in my 2004 Toyota Highlander limited. Heat and AC work great still and always have. I need more coolant once but that is it.

For posterity: I was able to replace OEM 84010-48180 with OEM 84010-48270 in my 2004 Highlander and it worked fine.

 

Dclynds, thanks for following up on your resolution. The A/C control panel (84010-48170) on my 05 Highlander LTD is beyond repair and your post gives me the confidence to eBay a used unit with a similar model number.

 

Hi kegg•sudsman, were you able to replace your 84010-48170? Did you replace it with a 84010-48270?
