Replying to: runuts001 (Sep 07, 2006 12:02 pm) hey, got two problems with a 2001 jimmy. Problem (1) : Last year about the this time, I had problems with my heater....no heat. Through you guys I found an easy fix with radiator cleaner...but oops, I don't think i flushed the radiator good enough now it sounds like i have a engine full of canaries until the engine warms up for about 20 minutes. Is there anything I can do   Problem (2) my brake warning lights stay on and the car sort of has a bounce and a slight erk in the seering wheel... whats that about?

Replying to: jonesvm (Nov 18, 2006 1:41 pm) If the heater core gurggles it needs to be flushed and you can do that by buying a 3' length of 5/8 and 3/4 heater hose, cover distributer with plastic, and remove the 2 hoses at firewall and flush with a garden hose both ways till runs freely. Hang the ends over the fender and simply hold the garden hose to the heater hose while on with your hand wrapped around so not high pressure to blow the heater core. That is the red brake warning light I guess and probably the emergency brake pedal is not fully releasing so see if their is something hanging up above the handle. If ABS post back.

Replying to: jmeade (Dec 06, 2006 1:56 pm) Probably a clogged heater core so do as in post 6 above.

Replying to: repairdog (Sep 07, 2006 1:57 pm) It looks replaceable, but where Can I buy one. I think I pulled wire too hard while doing some axle work. Replies to this message: repairdog (Dec 19, 2006 3:23 am)

#11 of 39 2001 BLAZER ABS by diablo3 Jan 08, 2007 (3:15 am)
THE BRAKE PEDAL ON MY BLAZER PUSHES BACK TO ME WHEN I APLPY PRESSURE AT 10 MPH OR LOWER AND MAKES SORT OF A GROANING NOISE. NO PROBLEM AT HIGHER SPEEDS I CALLED GM AND THEY TOLD ME IT'S PROBALLY A WHEEL SPEED SENSOR TO HAVE THEM CHECKED AND CLEANED OFF AND THAT WILL SOLVE THE PROBLEM. I WENT TO A DEALERSHIP AND THEY TELL ME IT'S THE ABS AND THEY WILL HAVE TO REPLACE IT. I HAVE AN APPOINTMENT FRIDAY TO HAVE THEM CHECK IT. IS THE DEALER TRYING TO RIP ME OFF ASSUMING THAT IT'S THE ABS WITHOUT CHECKING IT YET. I'M SURE A WHELL SPEED SENSOR CLEANING OR REPLACEMENT IS A LOT CHEAPER THAN REPLACING THE ABS SYSTEM.

Replying to: diablo3 (Jan 08, 2007 3:15 am) Have to read the codes out with a tech 2 scanner first to confirm. If in salt use areas the rust builds up and raises the sensor out of spec so have to unbolt the sensor and carefully sand the mating surface and not get any crap in the hole and in the hub, if thats the problem. Check the wires from the sensors up to the connector on the frame for cuts first on the fronts. Rear sensor is on the trans 2wd and transfer 4wd. Hub bearings (one piece asembly)going may also cause this but you would hear it also normally.
