all 4 windows will not roll down when you press the buttons on the driver side master switch. what can i diagnose to test if i need a new master window switch?

 

check the fuse. the master switch is pretty pricey. rule out the cheap stuff first

 

i see this master switch fail commonly, But CHAWSKI is correct, fuse continuity with test light/ meter and swapping relays is always better than replacing a $100 switch that isnt the issue. i can give u a master switch test procedure if interetested

 

yes i would like diagnosing procedures please. what fuses and relays am i looking for?

 

i put a test light on the power window 50 amp fuse under the hood and it is getting power

 

fuse 27 (20a) was blown. replaced it and now my driver window works. no other windows or power locks work though

 

i replaced the master window switch and all my windows are working and i can lock the doors from the master window switch. now my keyless entry will not lock, unlock, or open my trunk. i replaced the battery and it still doesnt work. my backup keyless entry doesnt work either

 

You need to program the key fob to the receiver.

 

how do you program the key fob to the receiver? Is there a YouTube video or written instructions on how to do this that you could reply with?
