Location of Front air conditioning drain line on Chevrolet Tahoe?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.



The details are as follows :----
The drain line should be under the floor pan just about below where the passengers feet would be. You should see a short piece of hose hanging down near the frame rail by the firewall.
However, if your CAR AC is blowing warm air, there will be no condensation dripping anyway, because your evaporator is not cold. Unless of course the problem is in your plenum mixing door.
It sounds like you have a/c issue.
