My passenger rear window switch doesn't work and I can't even control it from the main up front. Amy suggestions where to purchase one ? I saw one on eBay for $9 bucks but it's from China

 

I got one for my passenger side window off eBay for 9.67. Worked like a charm, simple as unplugging old one and putting new in. BUT my drivers control still worked it. I'm not 100% sure but if your drivers control doesn't work it you may have other problems than just the switch.

 

Ok thanks

 

The regulators failing is also a common issue with these trucks. Not too bad to replace either

 

I just replaced all mine in my (new to me) 04 FX4. I replaced them because they didn't light up. The OEM costs a small fortune, but I found a good deal at www.switchdoctor.net. I replaced the drivers side cluster for $22, and then got 4 singles (passenger side and back seat) for $14 each. Took 3 days to get here and 10 minutes to install all of them.

good luck!!
