Question about 2000 Chevrolet Impala
Recently power to the Heater/AC/Blower control panel is erratic, sometimes comes on immediatly, sometimes a few seconds or minutes later.
This is the solution if your car sometimes has unexplained water on the passengers side floor after it rains and the Blower is working erratic.The solution lies under the large black bezel/cover below your windshield wipers. Under this bezel on the passengers side is a piece of weather stripping that has fallen off. You will see it right away. If you fix this and replace your blower motor and resistor your HVAC will work correctly again. I spent a year trying to figure this out.
Just remove the bezel and check the weather strip. You will be able to see where it was by the discoloration. It falls off by poor design and allows water to seep into your blower motor shorting out the resistor and if left unchecked will smoke the blower motor also. You want to add some silicon sealant and replace the weather strip to it's original position.
As far as the blower motor and resistor it is not all that difficult to replace. You will have to lie on your back on the passengers side to get at it. It's very uncomfortable.
Good Luck !!!

Mine does the same thing. The blower never worked on 1 but always on 2. A few weeks ago, It started only working on 5!! I haven't taken it anywhere, but my dad (who is very knowledgable about cars) says it's probably the switch in the panel. Hope this helps!
