Power Windows/Locks Problem

Hello, new here.

I don't own a Honda but am doing some repairs on a friend's CRV as he isn't able to physically do them himself.

I've surfed around the site all morning and didn't find anything that I thought would help so I'm posting here.

The problem is that the power windows and locks do not work.

The history of it is the drivers side window started to intermittently not go up. Apparently this was most common during damp or extremly hot weather.

After a month or so of that, all of the windows had stopped working as well as the door locks. The locks work fine manually and there is no sound from any of the window motors engaging.

He purchased a used (confirmed to be working) window dash control module and I installed but it didn't work any differently.

So, my question is: where do I began to trace the problem and the location of any components I should be checking?

I appreciate and thoughts or advice anyone may have and thank you for your time.

PatrickWelcome to the forum! :)

What year CR-V is this?
Since all of the windows are not operating, how much have you looked into the fuses? Sometimes it worth testing a fuse via ohm meter rather than just a visual inspection.
Carefully check the wires going into the driver's door for breaks.
Slow movement during damp weather is relatively normal and can be solved by a light spraying of the window channels with pure silicon spray.

Nice, exploded diagrams are available here:

It's a 1998.

The fuse appears to be good but I'll check it with a tester.

Thanks.

To trouble shoot the problem the best tool would be a volt / ohm meter. Then you start your search. For example if the fuse is good, is voltage getting to the fuse? If it is, is voltage getting to the switch you use to open/close the window? If it is, then is voltage getting to the motor that moves the linkage to open and close the window? If it is thin you likely would have a motor problem, now I'm not saying you have a motor problem, just with that quick trouble shooting you would have isolated the problem to the motor. Once you find the point of voltage to no voltage then you work between those points, working back toward each point until you isloate the problem. I did not look at the circuit diagram, there may be a relay or even several, etc....If you dont know how to use a volt ohm meter or do not have one that will make things harder. Also a circuit diagram would help a great deal and the knowledge of how to read it. Well lots of luck.

Thanks for the reply.

I hope to get a look at it today or tomorrow.

I do have a multi tester so that'll be no problem and I've been trying to find a diagram with no luck. I have no idea where relays(s) could be.

One question; could the operation of the motor in one window have any effect on the other as none of the windows work?

Thanks again.
