We have an 01 Impala and the other day the climate control buttons (fan control 1-5, hot/cold, air...) everything- just stopped working. When you turn them it does nothing. Do you know how to help?

I bet if the problem is isolated to just the climate controls (and no other electronics), you'll end up replacing that whole unit there within the dash.
Seems like before when I had a problem with one of my bulbs burning out I posted a question about trying to get in and replace the bulb, and someone replied that it's a complete unit that can't be opened up and fixed, so you have to replace the entire controller. For a light bulb it wasn't worth it, but if my AC wasn't working in the 100+ degree weather we're having currently, I'd probably spring for a replacement.
I had a similar problem with my previous '89 Toyota Celica; I tried getting a used part at a junk yard, but the used part didn't work either, so I ended up ordering a new one (which was probably 10 years ago, and it cost  $400). Not sure what the part would cost today on a Chevy, though.

I am having the same problem with no driver side heat. I purchased the actuator as previously posted. Was curious if anyone had any experience changing it to guide me in a direction to get to it easily.

This will let you know how to replace drivers side or the passenger side actuator. Passenger side difference is noted at end of this letter. My 2004 Chevy Impala driver side climate control was stuck on cold, no matter where I switched it to. The light on the panel was also out. Resetting by disconnecting the battery did not work. I had to buy and replace the drivers side actuator (Part Number 15844096 - $38.46 at Chevy dealer). The passenger side actuator is also the exact same part number. They are both located under the dash, about equal height as the climate control knobs. Make sure you disconnect the positive cable on the battery before removing the switch. Drivers side actuator is accessed by removing the bottom dash cover on the drivers side. Two easy clips to disconnect the dash cover, remove the floor courtesy light by twisting, and the cover comes right out. The drivers side actuator is harder to work on than the passenger side, due to room. But I replaced my actuator with only having to take off the bottom dash cover. There are two screws holding the actuator on. I used a 1/4 hand driver with a 3" extension, a 1/4 universal joint for the 1/4 socket (and the universal is needed), and a 7/32" socket. These were the only tools I needed. After unscrewing the two screws, I pulled the actuator off of a small arm it is connected to which switches the flap for the climate control system between hot or cold. I then was able to let it hang down, and disconnected the wire running to the actuator. Room was an issue, and I did some of this by feel. Now comes the tricky part. The new actuator has to slide back on the small arm, but it is flat on two sides, with rounded ends. The new actuator has to match the flat ends to the same position as the old actuator. I hooked the wire onto the new actuator, and let it hang down. I held the old actuator up by it, and had my wife hold the battery connector to the battery to get power. The new actuator will rotate when the connection is made, and stopped rotating when I had my wife pull the connector from the battery. It took a couple tries, but I finally got it to stop at the same position as the old actuator. I then lined up the new switch, and got it on the control arm. This took a few minutes and tries, as I had to do it by feel. I then put the two screws back in and tightened them down. Again, tricky due to room. Once done, I put the cover back on, reconnected battery, and warmed up the car. Was very happy to find that I now had heat on the drivers side, as Michigan weather is cold this time of year. One note is that even though I now had heat, the light on my drivers side control stayed out. I can live with that though.
The whole job took me about an hour and a half.
Also, note if you have to replace the passenger side actuator, you need to remove the passenger side bottom cover on the dash. You then remove the glove compartment door by removing the five screws on the bottom of the door. Slide the whole glove compartment door out of the car. You will be happy to know you have much more room to replace the passenger side actuator, so it should be much easier and quicker than the drivers side.

i hade the exact same problem with my 01 and fixed it! VERY EASY you will need a 1/4" ratchet with a swivell and extention underneith the dash on the passenger side you will find the blower motor once you pull out that clip in plastic cover .. remove the blower it should be three or four screws cant remember exactly. once this is removed you will see at the upper most part inside where the fan was towards the driver side there is a "plastic wire harness" where your six wires from the fan controll come in and leave out to two that go straight to the blower motor its self. there are three of the same size screws holding this in. pull that part out and call your local gm parts dept. with the part number. i tried calling auto zone and advanced where i live but this is not a comon part. the gm place had it in stock for about 50$ and everything works perfect. my friend had the same problem with his 00 grad prix took it in and they charged him about 400-450 he was not happy.. hope this isnt too late good luck

This is how General Motors is getting people to buy new cars (hopefully you didn't buy another GM but we did) Had a 2000 Tahoe Limited with very low miles and right after the warranty ran out the computer locked up and the car wouldn't turn over, cost us a 600.00 trip to the dealer and a four day wait on the part so in the meantime we just traded it in on another.....Have a friend that this just happened to on a 2006 Equinox right after the warrnaty ran out GO FIGURE, they are programming this stuff to stop working and then you get irritated enough you just get rid of it.

Hi All,
I am new here to the forum and needed a little advice. I have an 03 Impala, base model with 55K miles. Last year I had my AC charged it was the first summer I had the car and by September it wasnt getting cold. Does it need to be recharged?
Thanks
