I did test drive the 26 and it did not make the noise.
The tech I went with thinks its an electrical issue maybe some bad shielding somewhere but replacing all the wiring is not worth it. So. Ill take the trade but I know they're not going to do that for everyone.
Good news and bad news.
Bad news they cant fix it. Some 4Runners do it some dont.
Good news they're giving me my full purchase price towards a 26 and doing this with the one I picked will eliminate my loan. So. No fix just a negative vehicle characteristic.
I have this too and took it to the dealer and they couldn't replicate because I didnt realize it was only when the windows are down. Id be interested to see what this is if anyone goes.
Also I did have heavy shifting investigated at stary of day and they deemed it a vehichle characteristic...
