My accord tourer ,rear powerd hatch isn't working also the passenger elelectric window won't work and the wing mirror too ,
I have heard this is because of the the passenger window switch ,I have replaced the switch which hasn't fixed it .
Can anyone help ?

 

It is probably best to treat these as individual problems and start doing some electrical testing to see why each item is not working.

With newer cars, a wiring diagram is required to do testing. A scanner can help in most cases, but something that can command the power hatch, mirror, etc is probably too expensive for a DIYer.

For electrical testing, look for power and ground at the component that is not working to help track down the issue.

Also, was any work done on the car before you had these problems?

 

The car had had water ingress at some point
I am not sure if this is the cautë of it

 

There can be wiring/connection damage due to corrosion depending on where and how much water got into the car. You will still have to find out if the component not working is due to lack of voltage, lack of ground, or lack of signal. Most circuits on newer cars have a power/ground to work the component and most likely a network signal from a computer/control module to switch the component on. The power/ground is the easier circuit to test to diagnose.

 

Thanks pa honda ,
I think it's probably beyond my capabity
I have called in a Auto electrician he's looking at it on Monday, i will let you knowhow he gets on
