Where is the sunroof drain located on 2002 monte carlo ss and how do i unclog it?

The way I did it was I used an air hose and blew out the trash

Open the sunroof and find the drain hole get a high pressure air hose with a blow gun and push air down the hole it remove the blockage.

If you drop down the headliner I think the drain hose runs to the rear and comes out in the trunk ? But can be blown out with compressed air from sun roof .

Sounds like it is going off track whenever it gets to the popping sound point. Or its catching against something, Check to see if anything could be in the tracks of the sunroof. Hope this helps, James Booth. Let me know what happens

Hi, very likely you have a leak from the wind shield and these can be proven or disproved by running tap water on the passenger side of the windshield. If the windshield is leaking a technician should be able to reseal the strip around the windshield or replace the windshield if its broken. Thank you for using fixya!

Yeah, there is a condensate drain that will get plugged up with stuff ( a leaf was in mine) Its frickin hard to get to though. but check to see if the water feels COLD. In my case, the location was right of center ( passenger side) see a plastic housing with a tube going through fire wall or disappearing into the carpet? the bottom of that tray collects condensate from the a/c coils and drains it to outside. If the water is HOT, and you smell radiator fluid, then you might have a heater core leak. Maybe this will help you nail it down.

there are none. you either have a bad heater core or your air conditioner drain hose is clogged. It should be draining above the shock on the passenger front side.

If it is just water start with the AC, if it has coolant in it then its the heater core.

The drain for your A/C may be clogged causing the water to accumulate. You should be able to locate the drain from under the vehicle on the pasenger side, perhaps there is an accumulation of debri such as leaves for example. Also, sunroof drain may also be blocked. I can say I have seen this problem before, and its a good place to start. Good luck

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.

Have someone remove cowl or cover to access cabin air filter box area, and clean it out good. Build up of leaves & other debris has been known to cause leaks inside because of drainage plugged.
