Check your coolant level and have the water pump checked, could also be a possible restriction in heater core

SOURCE: leaking water from front passenger side, under dashboard

It is either condensation water from the A/C unit that should go out a drain tube to the outside (only if A/C or Defrost is on) or a leaky heater core. If it is a heater core you can usually smell a coolant smell and the water will be warm and your windows will fog up inside. Heater core is more common. Joe ASE Master Tech

SOURCE: water is draining from under the passenger side dashboard

Does this happen when it rains or you go through the car wash? Or does it happen when running the A/C?
Let me know.

SOURCE: fluid leaking onto the front passenger side floorboards.

2004 TB 60,000 miles. i was just told that the leaking fluid in my passenger side floorboard was do to a clogged up A/c hose. An A/C works by drying/ removing the moisture from the air inside the vehicle and cooling it. The accumulated fluid is usually evacuated under the vehicle which is what you see when people are stopped at a red light and there is dripping under their car. when a hose is blocked there is a vent that from some reason flows directly into the passenger side floor board. If you can not manually knock loose the block your probably going to have to take it to a mechanic.

SOURCE: There's a knocking noise coming from my dashboard

It is probably the blower motor itself, does it change sounds or quit when operating the fan? possible debris is in fan cage, fan has a bad bearing, or a blade balancer slip on weight fell off. remove and inspect, possibly plug fan in when removed and check for operation,while fan is removed check housing compartment for debris or foreign material laying in the bottom, check fan blade for signs of rubbing contacts or broken fins

Ticking noise appears to be coming from passenger side under dash, slight but annoying rattle


It might be a restricted or dirty blower motor. Is your heater or ac running? If so, turn it off to see if the noise goes away.

2001 Jeep Grand Cherokee Larado has water pouring out from under the dashboard on the passenger side. Help!


The water gushing in on passenger side, is probably antifreeze, check that the heater core isn't leaking. If it is gushing try and capture some of this water and and see if it is antifreeze or just water. If antifreeze then it's the heatercore if water the. It's from the a/c

Coolant leaking somewhere unknown, have to add to reservoir every 3 days or so, strong antifreeze smell with a/c on. water sloshing sound in passenger side dashboard. bad heater core?


sound like a bad heater core! the heater core is like a small radiator that is usually locaded in the dashboard on the passenger side. now if the leaking is really bad you are going to see water dripping by the front passenger tire or if it gets really bad it may leak inside the car. in order to fix this problem the HEATER CORE must be replaced. good luck

When I make turns tothe left, several things happen. First there is a noticeable drop in the pressure of the air coming out of my air vents(this is while my AC is running), and then there is an odd noise. ...


1st you need to identify the fluid in the floor board, is it antifreeze, water, oil?? 2nd is the leak there without turning the steering wheel? (more than likely). If the fluid is antifreeze, then yes it could be your heater core, the entire dash will have to be removed to access and change it so it will not be cheap to repair. If it is water, check and clean the a/c drain tube at the lower right hand side firewall under the hood, and check to see water coming out of this tube while a/c is on. Hope this helps, let me know.

I had a Fiesta once with a very similar problem. It turned out to be coming in around the seal of the windscreen. I solved it by lifting the seal with a spatula and thoroughly drying the glass and seal (on the outside), and then running silicone all around the edge of the glass, under the seal. (I used black but it wasn't visible anyway). This sorted it for me.
