The AC drain will be in the same place.
As for the battery vent tube for the hydrogen and oxygen fumes while charging, it should be venting directlyl below the battery, not over by the passenger rear tire. And it should only have gases in it, no liquids like water.
Good luck with spending time under the car--remember use jack stands or ramps to hold car up to give room. Wait till hot parts cool to crawl under!

I'm having heater control problems on a 1999 LaSabre. I believe it to be a vacuum prob. I dropped the glove box. and found a vacuum manifold of some kind. It has orange,black, white and green tubes on one side with a pink fitting broke off. the other side has a pink tube shoved into the opposite side of the black line. no other tubes on that side. any thoughts or idea where i can locate a vaccum diagram?

Are you describing a dual control system or the manual system without the digital readout?

I have a 2003 Buick Lesabre Custom and the fan only works after hitting a bump.
Where is the module located, does it need replacing or is there a short?
Any help is appreciated.

fan motor is above passenger's left toes. You can see the round bottom of the motor throught the plastic sound shield under the dash. Tapping this area with your toe will sometimes start the motor again when the key is on.
The motor's brushes may be sticking in the channels, the motor just may not make contact, or the connect from the motor to the hvac box may be corroded from heat damage. You might check the connector after you take off the sound panel.
But 3 screws hold the motor up in place. IT's a medium job because you're lying on your back to reach under and work on it. It's fairly heavy to lift into place and get the 1 inch tube the carries air back to the motor for cooling it in place. But it's doable. Autozone had the replacement motors when I looked for mine.

I need your help. My 97 buick lesabre has no heat or ac the panel on the dash is completely dead no lights no response when buttons pushed. It is not climate control. I have been on this forum for several days trying to fix the problem. I have no power to the panel. I ran a by pass wire to the blower switch still no results all relays and fuses check good The controller under the dash with the vacuum lines has a 12 volt power wire and when it is plugged in there is about three to four votes that goes to the back of the panel to several wires. What else can it be? Oh I have tried another switch panel same results

Fuse #5A Auto A/C Cruise 15 amp
Fuse #5D Base A/C 25 A
both in driver side fuse block under dash The number tells you the row and column.
the other thing is the one relay for the heater motor could not be pulling in. It's the one with 4 wires. It has two brown wires for low power for the primary coil and the high power ines are brown and Lt Blue.
The other relay for blower has 5 wires because it's a double contact with the primary wires orange and black and high power purple, DK blue, and RED.
The relay pulls in to provide low power to the blower speed switch otherwise there's no contact. I suspect it pulls in when the ON button is pushed for heater or AC.
I suspect this because you do not say anything about the high blower speed working.
This is the relay center
The relays have a tang on the bottom that snaps over a ridge to hold them in plane. Use a long steak knife type device to hold the tang up and they slide forward and out with enough wiring on them to inspect.
The suspect relay is interchangeable with the horn relay or the AC compressor relay. So switch them. I took the cover off one long ago and found the contact was burned on the relay so it wouldn't make contact--this was on the the compressor relay.
The other part is ground. Ground 202 is beside the parking brake area. There's a bolt screwed into the body the way the picture looks.

Thank-you for your response I switched the relays today, but was not aware of the fuses under the dash I don't have any thing that tells me what they are for. So your info is very helpful.

Note the correct location of Ground #202. I had the wrong ones.
