I bought an 02 Blazer a few weeks ago and just installed heated seats... mostly. When I tapped into an accessory power wire under the dash, the seat heater switch just flickers-- I don't think it's getting enough power. Where can I find a good accessory wire under the dash (not too far from the center floor console)? Thanks in advance for your help! I've looked everywhere for this...

 

just run a new hot wire with a fuse in it. check to see how many amps the heaters take when running on HIGH. and make sure that you run the right size wire and correct fuse. dont forget to double the amp value of one seat heater so that you can run the right stuff the first time. you dont want to have to try and fix it after you have already spent the money to do it once.
