Put new heater blower motor in ( got hot and melted wires among other things) After this the water would come in along the inside of the firewall. We opened up the drains to make sure it was working also applied silicone on exterior such as where window meets the cowling. Is there something else I should be looking for ?

Re: water leaking in on pasenger side floor
It sounds like you may have pinched the 12 volt wire that supplies the blower motor with power, and the seal between the motor and housing is letting in water. Try removing the blower motor and look for the pinched wire where it may be short circuited, and reseal the motor to the housing with a new gasket or silicone sealer.

A couple of things to check. your temp selector lever, knob from cold to hot. make sure it is moving the selector and opening to let hot water into the core.. Check listen for vacuum leak and move the controls for defroster floor etc. and listen to see if they are actuating ..these are usually vacuum operated but some are cables that get stuck at the heater temp valve. Hope this helps mike
No,your problem is the blower motor resistor that is either faulty or it has a bad connection.These resistors get hot and melt the pigtail.You can try and wiggle connection with the ignition and the fan switches on and see if it comes on. The resistor should be at lower right side of heater box near the floor on passemger side.You should see the pigtail going to it.
disconnect the blower motor. if the fuse is ok then, the blower motor is bad. if the coolant leak is on the passenger floor, you may have a heater core leaking, although you may also smell a sweet odor from it.
Sounds like you have a leak at the heater core and lack of heat usually means low water level in radiator. When engine is cold ,add some radiator "stop leak" top up the radiator, start the jeep but leave the cap off until the water is hot and you are sure radiator is full. Then tighten cap and drive or idle for about half hour or more. When you can afford it change out the heater core.
Find the drain for the A/C located under the hood, firewall, nearest the bottom of the firewall. It will be a black tube and if plugged, the condensation from use of the A/C (which also turns on when the defrost is used to evaporate moisture) will back up into the blower box and drain onto the floor. Long term effects include; rotted floor board, mildew, shorted blower motor and loss of effective defrosting, heating and cooling. Use a coat hanger or other long thin item to clear the drain and allow the water to drain. The system will be much more efficient. Let me know if you need anything else.
Check the blower motor resistor module,it is on the passengers side by the blower motor.Make sure and check the connectors to.They get hot and will melt sometimes.You can get new connectors from the dealership if they are melted.Hope this helps.Good luck.
the water leaking issue may have cause the blower operation issue. there is a drain for the a/c housing that comes out at the bottom side of the firewall on the passenger side of the vehicle under the hood that likes to clog up and build water in the housing. the water then runs into the blower motor causing corrosion in the motor and usually the connector at the blower melts as well. the blower is easy to change, the connector is not as easy but shouldn't be too bad. the blower can be found just under the glove box and has a 2 wire connector
i had the same problem. depends what kind of trim model you have. but if you look on the passenger side floor right under the glove box is where your heater unit is. if you take off the cover to it. their will be a little squarebox looking thing with 2 - 3 wires coming out of it and goin to the blower motor unit . Tap the square box with a screwdriver while your blower motor is on off mode. it should shut off if you give it a couple good solid taps. dont be afraid to hit it. that little square thing might have to be replaced if it turns off when you hit it. or just may have to be cleaned.
