OK, on most GMs the plastic cover is held in place by these little plastic anchors which when removed, sometimes get damaged so they have to be replaced with new, in general.

Also, the wiper arms come off with a screwdriver, but sometimes the tabs get bent, so they have to be bent back.

A windshield technician would know how to remove these parts without damaging it beyond repair.

If you haven't done it before, successfully, I wouldn't do it. Allow a technician to do it, you'll be happier, really.

Check to see if there are any 2" x 3" rubber flaps below located on the firewall where sand or dirt can accumulate, making it overflow into your cabin.

Has your car ever been sandblasted for paint removal? If it has, the drain is likely to be clogged. That's what happened to me once.

You might be able to avoid taking the plastic cover/vent off if the flappers are the only problem.

GM made cars this way in the 1988 Oldsmobile Cutlass Calais, anyways.

But, I haven't checked to see if they changed designs for the 2002 Malibu, and my online resources don't really cover the problem.

Good luck to you on this fix.

Water is running under my dash onto floorboard in my 2007 dodge caliber after it rains. Where is the water comming from


You need to find the conduits for rain - one of them has a leak in it probably from corrosion. Try to locate just where the water is getting in and see if you can use a sealer to stop the water from getting in.

I would remove the glove box and anything else in the way and look for the source when hosing down the car.

How to remove the glove box from a 2006 porsche cayenne


Replacing the fan doesn't take many tools, just skill. The fan is under the passenger side dashboard. Remove the cover that is held in with a T25 screw. After removing the screw pry the cover down. Disconnect the light from the cover. Remove the foot vent under the dashboard by pulling it down. Using a 5.5mm socket remove the screws holding in the blower fan. Removing the fan can be very difficult because the main wire harness goes under one edge of the fan. When you get the fan out check it for water damage. When installing the new fan make sure it slides into the channel in the hva/c box. Working around the wire harness can be frustrating. After reassembling check that the fan works. There are 4 places water can leak into the fan. The hva/c water drain can be plugged. The wiper cowl cover at the base of the windshield can be unclipped from the windshield. And one of the two wiper cowl water drains can be plugged.

The front wipers of my 1998 BMW 528i are not working


Hi angel,

I would recommend first starting with checking the fuse. The fuse for the wipers is located in the glove box. If the fuse checks out ok, I would recommend checking the wiper relay.You will need to remove the passenger microfilter cover under the hood. First remove the filter cover. Then release the tabs holding the delivery tube to the filter housing. The housing lifts up and rotates out out to the side. Under the housing you will find a white plastic cover being held in place with 4 allen bolts. Using a 5mm allen remove the bolts. Once removed, under the cover you will see several control units and fuses and relays. Look for the BROWN relay. That relay is for your wiper/washer system. They do fail after a while. When reassembling the cover. make sure it is seated correctly, if not water can enter the electronics and create problems down the road.

After a heavy down pour I noticed a large amount of water dripping from behind the glove box. Do I have a clogged drain?


The two drain holes in the compartment beneath the wipers are plugged with debris. Take off wipers.
2. Take of plastic panel under wipers. 3. Clear crud away from drain holes. Pour water in there afterward to make sure it drains properly..You will see it come out the bottom under the car.
4. Clean out any other leaves hope this will hlp you

PASSENGER SIDE LEAKS AFTER IT RAINS


If the water comes in from under the dash, the drain under the air vent on the hood is probably clogged. You have to take off the windshield wiper arms, remove the vent and unclogg the drain. Very poor design!

Water leaks from behind glove box onto floor


Three things can cause this.A leaking heater core,leaking windshield(when it rains,or has been washed),and sometimes not often the AC drain plug can be clogged.I would go with the heater core,look under the dash you will see a black plastic box with 8mm screws about 6-10 of them remove them from the bottom first and gently pull on the cover you should get water running out.Replace the heater core,if water present.

Floor board on passenger side door gets wet when it rains. i am sure a vent drain is clogged


The drains in the wiper wells are probably clogged. You need to remove the plastic 'vent screen' under the wipers to clear out the debris. Remove the wipers and a few screws, not difficult at all. Also, under the hood, you will see a vertical tube on each side of the car under the wiper wells. These can be removed from under the hood without removing the wipers, but you will probably have to clear the wells anyway. What happens is the water backs up and enters the car through the fresh air inlet and comes in around the blower fan. Good Luck.

2003 impala leaks from under glove box


If you want to know the where the water is coming from, water is entering from the passenger side front cowl. ( the vent below the windshield that sucks the air in for your a/c and heat) there is a recall where chevy installs a plate under the cowl and diverts water out. There is your answer.
