I just had the exact same thing happen with my 2000 Blazer ZR2. I removed the dash to replace heater core and when I put dash back in and put everything back together I had the exact same symptoms. I ended up removing my dash two more times trying to find the problem.
 Somehow now, im not sure why, when I open the passenger side door It will blow the fuse for my push button 4wd-domelight. So for a quick fix I just disconnected the wire going to the plunger at the door.
 I was able to get my guages working but im not sure how, That lasted about a month now there out again!!!!!!!!!
 This may be going in the complete opposite direction but after looking around online im kinda leaning towards a bad igintion switch.
 Please let me know if you find anything

YYEEESSSS I figured it out!!! It was in the wire box that conects all of the wires from the dash to the computer!!! There are three different connections but the one that was bad was behind the glove box!!! All I had to do was loosen the bolt that sandwiches the two halves together, disconnect it and look to see which wires were pulled out just a little more than the rest and used a screwdriver from the other side to push it until it looked like the rest of the prongs!!! I also had a wired that was completely pulled out of the harness, I just cut the wire and wired it direct!! Long story short, don't get pissed off and just start pulling on the dash like a maniac to get it out!! Better yet take it to a shop!!!!if you have any ?'s email me!!!!

Dude, just had the same problem with my 2001. I dont know if you tried already but,i reversed flushed the heater core with water and now the heat works fine.There was some gunk caked in there that shot out like a rocket when i did this causing the blockage of coolent flow thourgh the core .http://www.chevroletforum.com/upfiles/13312/05CE0996D5A54078B6D49EAEA08CB32F.jp- g This is the link with the info you might need, good luck.....

Hello I'm having a problem with my gauges. My fuel gauge is always jumping around unless it is full. And my speedometer has gone on the fritz. Ever since I went to Florida. When I got back home the needle didn't move until I got to about 30 mph then it jumped to 30. When I got lower than 30 the needle dropped back to 0. And then the needle won't move above 40 until I get to about 50 mph and the needle jumps to 70. Can someone help me figure out what is wrong. So I can get it fixed asap.

#152 of 185 2001 Blazer dash lights and gauges going crazy!! by traiford

Feb 26, 2008 (6:11 pm)

Just bought a 2001 Blazer from my boss. Stopped at store , then it wouldn't start. Finally got it jumped and as I was driving the dash lights and guages were going crazy. Every dash lights turning on, flashing, fuel, speedo, and tach would drop out and then come back . Took it to Autozone and they said alt. diodes were bad. Put on new alternator ...same thing. At idle everthing seems fine. Once I accelerate the dash goes crazy. Here is the really stange thing...I put it in drive...stand on brake and rev the engine to 2K rpms and no problems...its only when it accelerates with movement. FYI the battery still won't charge.
  
Please HELP!!

Sorry I can't help you on this, but wanted to add I have a 2004 Blazer and it just started doing the same thing on my way home from work today. I just dropped it off at the service center and won't have a diagnosis until tomorrow morning.
 
I am curious to here if anyone has any ideas on what would cause this.

The statement that it doesn't act up with the car sitting still, but only moving, doesn't make any sense at all. The only thing that could possibly point to would be a loose electrical connection in the charging system that is getting jostled by passing wind while driving.
 
How many miles are on the Blazer?
