How do I troubleshoot front passenger side power window that goes down but not up?

Asked by Jul 05, 2016 at 01:07 PM about the 2009 Hyundai Elantra GLS

Question type: Maintenance & Repair

The front passenger side power window in my Hyundai Elantra has been temperamental for a while now. For
the past year or so it has been able to go down easily from either the driver or passenger switch, but would go
up very slowly (or occasionally not at all). It finally stopped going up at all the other day (right before a huge
thunderstorm, of course).

I'm really inexperienced with respect to any car repairs so I'm hoping to get some advice regarding how to
troubleshoot this. I know the motor is OK because the problem persists when I swap it out with a proven
working motor from one of the other windows. I can manually move the window up and down by taking out the
motor and moving the gear (or the window) by hand, so the mechanical track part seems to be good (I think
this is called the regulator?).

I'm not sure how to test the switch outside of buying a new one (unfortunately, the power connector for the
passenger side switch is unlike the ones for the other windows so I can't swap them). However, it is my
understanding that the switches rarely go bad so this may not be the problem. Also, the window-up part of the
switch fails on both the driver and passenger side switches and it's unlikely that they both failed at the same
time.

I suppose there could be a problem with the wires themselves, but I'm not sure how to test this. I have a
voltmeter/multimeter but I'm not really sure how to use it. There are also wires that go into the engine
compartment and ultimately connect to the battery at some point (obviously), but I'm not sure what other
components may be in between and whether or not these could be the cause of the problem.

Any advice?

Usually the window regulator assembly needs to be replaced. The cable binds or breaks in most cases.

Thanks, Tom. I can see this being a possibility and I was on the verge of further disassembling the door to get at the assembly, but wanted to see if there were other things I could check first. One thing I noticed was that if I disconnect the motor from the regulator assembly but keep it connected to the switch I can make the motor move in one direction (which would move the window down), but not the other. Instead of moving in the direction that would move the window up, I hear a faint click inside the motor. For this reason, I don't think it's the regulatory assembly. If all was well with the motor, switch, and wiring then the motor should just turn the gear in the opposite direction, right?

Dan, I have the same problem with the same make and model. Did you figure out what was wrong and more importantly, how to fix it? I couldn't raise the window from either the driver or passenger side switches but if I clicked the switch (on either side) enough times it would eventually catch and raise the window. I figured it has to be a bad contact on the motor but haven't tried other working motors yet. Did you come up with a way to pinpoint the problem and/or rule out the regulator? Zack

Hi Zack, I haven't found a solution yet, but I've been away on vacation and side-tracked with some other things so I haven't really done much to investigate over the past few weeks. I can add that my problem started the same way where the window would eventually catch after clicking the switch on either side a bunch of times, so it may be a matter of time before it fails altogether. I'll be sure to update this thread with any new info.

I'm having exactly the same problem, 2009 Elantra Touring. I haven't been able to really test anything yet, as I'm away from home (and my multimeter). But my front passenger window is stuck down and I have to do something. Any solution?

Hello. I'm winding if there are any updates? I have a 2010. My passenger side window can only go down with driver's control but not up. Passenger side control works fine. I suspected that rain got in last summer when I mistakenly left the windows cracked while at work. Also had the same lead up to the failure, in that it was slow in raising the window from passenger side, until it stopped completely. Thanks

All I can say for sure now is that, for me, the window motor isn't the problem. I just replaced it, and I'm still having the issue (there went $50 for nothing). I'm thinking this narrows it down to the passenger side door switch. Take a look at: http://www.justanswer.com/hyundai/51wz1- hyundia-elantra-2001-elantra-gls-power- windows-problem-i.html

Graham - Any update? I would lean towards a switch/relay. The speed issue mentioned is likely because the switch is still bleeding toward the down leg of the motor (and overheating). I have the same (but different) issue. I can activate all the windows from any location. But I can only put the passenger windows up from the passenger side w/ confidence. In about 50% of time they go up from the driver side, but very hard to get up, and slow. it effects both the front and back... So I'm leaning toward the $100+ switch assy. Just thought I'd ask!

I have a 2009 Elantra. Starting have this same issue more than a year ago. Until last week I was able to "roll" the passenger window up using the driver side panel, while the passenger side panel stopped working some time ago. Now the passenger side doesn't go up, but does go down, intermittently, from the driver side. Today I replaced the window regulator motor, but that didn't work. However, for a moment the window rolled up from the driver side panel, but I couldn't duplicate the result more than once right after I connected the new one. I'm sending it back to Amazon to get my $50 back. To sum it all up, these are my findings: - the window regulator motor is not the issue - the driver side panel can, A. roll down the window (intermittently), B. not roll it back up - the passenger side panel doesn't roll up or down - my back right window also doesn't roll up from my drivers side panel For now I'm going to have to keep my passenger window rolled up and hope to fix it in the future. Also, I got the window rolled up by using the gear section of the window regulator (it fell off by accident while I was uninstalling it from the door) and turning it until the window was all the way up. I hope that helps anyone who's window is stuck in the down position.
