Just an FYI: Interchangeable Master Switch Assembly for Power Window Regulators

[oldcavendish]

There is a big price difference between these window regulators on PartSouq:
P/N #84820-60110 - $445.07
and
P/N #84820-60130 - $260.47

This video shows how to replace the switch, but you'll notice his original switch is the 110 and he replaces it with a 130. It seems that the auto-up feature on his aftermarket doesn't function, but it was like $25 and no longer available, so is it a part number issue or a quality issue?. Is auto up worth $230? That's up to you:

At PQ, use your VIN # to get correct P/N.
There are a few different master switches, based on make and year. Used ones are typically around $100 to $160.
If yours never worked from day you bought vehicle. Is it correct master window SW (someone could have replace with wrong one) or did it (factory installed) fail.

Not all 100 series are the same. Land cruise all 4 auto roll up, mid 2000. LX "may" have always had may not. Before that only drivers window auto.
