Hello there:
This leakage that youare seeing is coming from the heater core which means that you will need to remove the heater core and get a new one
The best way to do this is to Mark and disconnect the 2 hoses that are going thru the firewall to whick pipe they attach to on the heater core then remove the 6 or 8 nuts or bolts that hold it into place then you will find that the box that the heater core is sitting in may have some nuts and bolts on it to so remove them next the box itself needs to be seperated at the seam to assist in the removal of the heater core so cut along the seam with a very sharp knife or a utility knife and then remove the old heater core and install the new one then put everything back and dont forget to reseal the box otherwise you wont get much heat flow from the core de to air getting inside of the box ok then make sure you put sealant on the bolts where they go thru the fire wall and tighten it down firmly then reattach the hoses and you are done
Hope this is very helpful for you
Best regards Michael

Since I purchased my 2000 GMC Yukon XL 1500 we have had a water leak that soaks the drivers side floor and passenger floor behind the drivers seat. I took it to my GMC dealer and they had it two days and said they could not find the problem. I have checked everywhere but suspect the water is coming in somehow from the sun roof. Also my horn does not work, but when I lock the car with the remote the horn honks. Also Does my 2000 GMC Yukon XL 1500 have a cabin air filter. I looked under the dash a

You may be right about the sun roof. It should have 4 tubes to drain water that comes in around the glass. Sometimes the tubes fall off letting the water come into the cabin. The horn may be the part in the wheel. Apply it at different angles and it ... 2000 GMC Yukon XL

I have a 99 chevy tahoe that will not lock the doors unless I use the keychain remote or puch each lock down, same with unlocking. The lock button on both the driveside and passenger side do not work. Also my rear hatch button does not work either on the remote or on the button on the dash. When pressing the rear hatch remote button I hear a clicking sound from behind the dash. Both problems started at the same time. Could it be a fuse? I was driving on a very dusty road prior to the problem.

With regards to the lock bittons on the driver and passenger side its the button themselves aka switch(s) that is your culprit. Why because the remote is getting the motor to open and close them . The only thing that doesn't is the buttons /switche ... 1996 Chevrolet Tahoe

Hi, thanks in advance for any assistance! We have a 2003 Saturn LW, and the floor on both the drivers & passenger sides get really wet.

I ask because the A/C was recently fixed, a part had to be replaced. Any suggestions? Many thanks!
