So i wanted to clean out my cowl but I could not figure out how to get in there. Any suggestions?

 

Check out what the PO did to my car before I bought it.

The least evasive (non-removal of welded metal) way to clean out the cowl is to remove the front fenders (just about the entire front end sheet metal) to expose a rubber plug on each side. Remove the plug and poke and pull out as much as you can. Then blow air (never water) into the cowl grill and plug holes and all kinds of remaining other stuff will get agitated and may fall into the heater (not good) and the left side vent and onto the pedal area. A combination of air into the plug hole and cowl grill is about all you can do.

Cool Thanks I appreciate it.

 

It's probably for an alarm.
