Default 2000 LS Heat and Cruise not working. Help ASAP Please!

A couple weeks ago my heat and my cruise were working perfectly fine and just recently they both have stopped working. Sometimes they will come back on but itís always both at the same time. Iíve checked all my fuses from my AC/Cruise fuse and even my BCM fuses just to be sure it wasnít something odd like that. Needing help ASAP as I live in the Midwest so itís already cold and just gonna get worse. Thank you much!

A couple of years ago, my 2006 Trailblazer had a similar issue. The cruise control stopped working. After extensive investigation and no solutions, I gave up. One morning, my wife was driving in front of me on the way to work. I noticed that the left brake light was out. Spent $17 at AutoZone and magically, the cruise started working again. Turns out the culprit was the circuit board in the tail light. Go figure....

is the blower motor not blowing on all speeds what you mean by heat not working?
Reason I ask is I had a similar issue with cruise/blower motor being stupid on an 03 monte, was a strange fix but it was in the ignition cylinder. The electrical part not the actual key part. I also noticed when I had this problem it was random, may do it one day and not again for weeks. also the driver info center up by the rearview mirror would go nuts when the problem arose.
Must be a ground that works that stuff through the ignition switch that was going bad.

Iím sorry I shouldíve been a little more clear, yes itís just not blowing at any speed no matter what. And where is that located at a little more specifically if you can. Thank you very much for your help

The ignition switch I was referring to is in the dash. Its the part you put the key in to start the car. But you just need the electrical part not the entire lock cylinder if that helps make any sense. If this is indeed your issue the good thing is its not expensive, if I recall the switch was around $40. I replaced it myself took maybe 30 minutes if that.
Google a video in youtube and it should help. Just search for 00-05 monte or impala ignition switch replace.
