#15 of 24 Leak on passenger side of HHR
Jul 19, 2010 (5:04 am)
As described by the other posters, water would poor off the windshield and under the cowl cover. Also as stated, it's the ridiculously cheap rubber cover over the heater motor, The adhesive had failed and it had collapsed allowing rain to poor in. I went to my local hardware store and bought a sheet of aluminum, used the old cover for a template then sealed it all with silicone caulk. Total cost= $7.54 for the aluminum and an hour of my time. (I already had the silicone) Seems to work fine and it won't collapse like the rubber cover it replaces. Hope this is helpful. Even though the car was assembled in Mexico, the engineers in Detroit could have avoided the problem at very little cost. metal cover? rigid plastic?
#16 of 24 2005 HHR water leak
Aug 16, 2010 (5:13 pm)
My HHR is a great car but 10 months ago the passenger side floor board filled with water after a storm in the Pittsburgh area. The car has 38,000 miles on it. There has never been an accident that would have caused this problem. The Washington PA dealer said they had a leak expert whom they brought in and supposedly fixed the problem. The car did fine through one Pittsburgh winter but the leaked recurred with a storm last night. I called the Washington Chevy dealer and simply was given the name of the "outside expert" and told to call him directly. Seems to me that I am not the only one who has had this type of experience based on my review of this blog. Shouldn't GM take care of this regardless of warranty? Is there a GM technical bulletin out there? Why would the dealer not repair this themselves? Obviously it's a serious problem for an otherwise fine car if it is not taken care of properly. Any suggestions?

Please see my posting from today. I am the owner in CA. My daughter is in school in Pittsburgh. I am not in a position to fix this myself. It sounds simple. I think you should authorize a dealership in Pittsburgh (more convenient to her now than Washington PA) to take care of this.

it was a blocked sunroof drain in my car ......we have alot of oak trees that drops fine particals every spring and clog up the drain,,,,,,,,,
since i found the cause, i insert flexible tubing that i got at a aquarium store into the drain holes on each side of the sunroof and blow compressed air thru them..
then i pour water into that area to make sure that it drains....
when they are clear, the water drains out as fast as i can pour it in..
#19 of 24 pool of water on passenger side; a/c and lights are shorting out

Glad to know I'm not the only one who is having these problems. Thanks for the helpful hints and insight.
My daughter drove it tonight and told me that, along with the pool of water, the a/c not working, now the lights are shorting out. Hope I can make it until it gets fixed. What a mess!

My passenger sunroof hole is keeping water, I tried to open with a plastic stick but has resistance. How you changed the pipe to replace the old one? How I can open myself the inside layer?
Please help me, I am overseas and technicians dont know this type of car.
#21 of 24 water on drivers floor
Sep 10, 2011 (3:49 pm)
I have a 2010 HHR. Its been raining all week and I noticed a mildew smell when I got in it the other day. Put my hand on the carpet and its soaked. Its only on the drivers floor. The crpet and padding is completly saturated. Any ideas on what this could be and is it covered under factory warranty?

Did you read through the earlier posts in this topic?
talks about a cover over an opening into the HVAC box. It requires taking off the plastic cowling under the hood to get to it to be sure it's sealed. It's located where water that enters the cowling below the windshield can get to it during a rain.
Do you have a sunroof with those problematic sunroof drain tubes that go down through the car?

Ok the water leak into passenger side from what I just found by fixing mine is due to a cover slipping off the windshield side of cowl there is a big plastic cover you have to remove first. remove wiper blades plastic covers at bottom of blades pop ff then 2
15mmyear nuts put blades back on in location they came off remove 4 7mnem screws from black cover then in the 2farattic corners of cover there are push pins pull and save to put back in compress wire clips along front edge and push back though cover lift cover off twist and slide out far enough to access left side cowl cover here you will see water problem there is a piece of plastic its fell in from the bottom of front window and you can see ac evaporator this is the issue that is causing 90% of water getting in its supposed to cover themselves big hole on left side of cowl its attached with butel rubber but it looses its adhesion and falls in which create a funnel effect and diverts the rain water that comes in right into heater ac box to repair remove cover and wash leave butel. apply clear silicone to outside edge of cover on the side with butel clean area were cover fits on cowl as well stick cover back on car now you need metal duct tape not cloth or plastic 4inchcover wide works well now tape all 4edgesupdates of cover half of tape on cover half stuck to car and windshield bottom below bottom edge of large black cover you removed once that is done reassemble. it should stay dry then water does gerontocracy cowl area under cover but it has drains for that when that piece falls in it covers drain and directs water into heater ac box poor design it takes less than 1hour to repair 1remove tube clear silicone 6ftto metal duct tape 7mmnot socket nut driver 15mm socket. with rachet plyers good luck take your time clean areas well clean cover bead call along bottom of windshield wait for silicone to cure then tape edges not before.

I believe there is a mis-diagnosis of the problem here. It is NOT the fault of the rubber cover. That thing is not intended to be a perfect seal but only to keep out the leaves and twigs. The real problem, as I found on my 2006, is that the passenger side drain in the large cavity gets plugged with leaves and "helicopters". They get there by passing between the windshield and the large plastic cover. There is wide open communication to the passenger side of the cavity from the drivers side and so the air flow to the blower motor pulls the leaves to the passenger side. Anything that gets by the windshield to plastic cover crack, can work its way to the drain. And that drain will definitely not pass leaves!!
Not sure of a good fix but if you have replaced the rubber cover with flashing or steel, be prepared to go back in there and remove it again to get the leaves out.
It's really no more than a twenty minute job to pull that plastic cover and then the rubber cover and clear out the blockage. So if I have to do that once every 5 years, I can live with that. I hope this is of assistance to you HHR lovers. We love ours.
