Hello Again. Every now and then i hear water dripping form inside the dash board when i take off from a light. Happens only when the a/c or heat is on. There is nothing dripping in the cabin, the underneath of the dash is not wet, and nothing out of the ordinary under neath. has anyone had this happen?

Thanks

 

If it is a water flowing noise, this is commonly caused by a restricted heater core. Sometimes a flush can cure this condition, but if it has been there for awhile, your core may be corroded to the point where flushing it may open up a leak.

If it is truly a dripping noise... That is odd...

 

Check your antifreeze level, and make sure it's not low. My water pump was going out last fall, and I kept hearing a gurgling sound. Also, heater wasn't doing much at all. I never smelled antifreeze, and never saw any leaks on the driveway, so my water pump died a very slow death.
