Question about 2004 Chevrolet TrailBlazer

Heater motor will not work on #5, it worked for 5days after resis

My heater motor stopped working on #5 speed and I was told that the heater resistor was bad so I replaced it. the #5 speed started working and I figured that problem was solved. 5days later the same problem happened again no #5 speed. All the other speeds work the same as before, When it was running on #5 the motor sounded fine and pushed out a lot of air more than it did on #4 speed the motor seems to be running fine when it was running. I thought if the motor is going bad it will sound like the motor wants to run slow when on a high speed due to the bushes getting worn...Can someone help with this PLEASE

    I had the same problem a week ago. It started this summer my #4 would not work, well now none of them work. Where I live it is about 12 degrees right now so I took it in. The problem is the blower needs replaced and my wires also need replaced because the blower melted them. GM knows about this problem they have posted a bulletin about a faulty blower in many GM made vehicles, but they will not cover it for you. Guess what it is not cheap to fix. Good Luck!!!

First check to make sure the electrical connector on your switch is o.k. if it looks burnt /brown or melted replace your switch, and the connector.If all is well then replace your blower motor, it may be drawing to much current (AMPS). Along with a new resistor block.

98 buick heater stop working


Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.


It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

WELL YOU HAVE TO USE A VOLT METER CONNECT ONE VOLT METER WIRES TO GOOD GROUND AND THE OTHER VOLT METER WIRES GOES TO EACH SWITCH SPEED.IF VOLT METER GET VOLTAGE A 1 OR 2 CONTROL SPEED RESISTOR BAD.IF RESISTOR BAD YOU WILL GET 1 OR 2 BLOWER MOTOR SPEEDS.IF BLOWER MOTOR WORKING.CHECK THE AC AND HEATER CONTROL SWITCH FUSE OR CHECK BLOWER MOTOR FUSE AND RELAY.IF ALL GOOD SO FAR CONTROL SWITCH ITSELF COULD BE FAULTY.

The fan on my heater/ac stop working on settings 1-4 for awhile it worked on #5 but has now stopped altogether


The blower resistor has gone out but if blower is no longer working on speed 5 then either the blower motor is bad as well or the pigtail connector to the motor are bad. Check the plugs to the resistor and to the blower motor for insulation damage discolored or melted wiring.

2002 Buick Century Heater Doesn't Turn On


replace the blower motor speed control resistor 1st then the blower motor if the resistor doesn't fix the problem. Below are instructions to replace the resistor.

The blower motor resistor is located on the back of the blower motor housing under the dash on the passenger side. It can be difficult to get at, but it is doable. Be ready with the ibuprofen the next day for your sore back. Remove the cover panel from beneath the dash on the passenger side. Unplug the power 'ribbon' wires leading to the resitor. Unplug the wires that lead from the resitor to the blower motor housing. There are usually two, one black and one purple that share the same plug. Remove the short hose that leads from the blower motor housing to the ventilation system ducts. Remove the blower motor by removing the three hex screws that hold it in place. Remove the resistor by removing the three hex screws that hold it in place. The resistor is right against the firewall so two of the screws are very difficult to reach. A slender flexible socket extension will make the job easier. Attach the new resistor in place using the same hex screws. Only 1 or 2 of the original three are needed (the part is very light) if you do not feel like fighting with the ones next to the firewall. Reatach the blower motor and reconnect the hose. Plug the power cable wires back into the resitor and the wire from the resistor back into the blower motor.

2000 OLDSMOBILE ALERO HEATER DOESNT WORK


The new vehicles with a 5 speed fan run all the speeds through the resistor and these are a very common failure. You should be able to buy one at any parts store.

Blower motor or resistor?


If it was the motor that went out then it would not blow at all. The resistor is the culprit that starts killing off speeds. It should be about $25 to $30 at an aftermarket store like autozone or advanced auto parts.

Heater not working


The problem is probably the blower motor resistor. I'm not sure where yours is located exactly. They can be on the firewall under the hood or some are near the blower motor under the dash.

Heat levels..


need new technician.if the blower motor works even with only one speed than the blower motor works and did not need replacement.sounds like blower motor resistor or resistor wiring,when there is a problem with the resistor or wiring you will only have one speed,this way you atleast have heat.so if your tech replaced the blower motor when it worked and did not need replacement then it sounds like he is just throwing parts at it,you have to wonder if he really checked anything.have the resistor and wiring checked and if ok then check the heater control head and wiring.
