You have leaves or a mouse nest in the hvac fan, the fan is a squirrel cage type and is out of balance because of debris in it, you can remove it pretty easily by removing the screws under the dash and it will drop down and you can clean out the debris

Weird noise and vibration in the dash when I turn my heater on in my 2003 Chevy trailblazer LS... When the heat is higher then the #3 setting it vibrates bad I can feel it all the way down in the petals......

Your heating system is broke in the dash. The doors or gates that change where the air is to go, has a broken hindge or actuator. Your heat is set to defalt to the defrosters as a safety thing. The vibration, I would say, is your fan & it may have been the thing that started your whole problem. The fan has something wrong W/ it, weather it has dropped, the shaft that it runs on is bad, or it is just going to the bad. To fix, the whole dash has to be dropped so that the gates or doors can be accessed for repairs & the fan, it's half in & half out of the passenger compartment. I've had 3 or 4 dashes out to do this work but it is TIME CONSUMING. Wish you the best, GOD BLESS.....

Suzuki Grand Vitare 2.0l. How to check why heater fan is not running

If the heater fan is not running;
1. Check the fuse first of all.

2. Check if the fan is running when connecting 12VDc directly to the fan.
If not running . Replace Fan.

3. If Fan OK - check the voltage on the connector from the fan between red and Black wire. Must be 12V

If no 12V - Supply voltage is missing - probably fuse defect.

4.If 12V = OK - measure the voltage on the Violet wire in the connector.
When button on dashboard is set to "Fan active" You must measure a voltage here close to 10VDc. If OK Fan Resistor/Regulator defective.
5 If no voltage (10V) on the wire (violet) when set to "Fan active" controlboard behind the dashboard defective.

Vibration noise from cabin ventilation fan

Pull the fan motor and look for debris. Sounds like a balance issue. Test the unit on a bench. If cleaning will not resolve, replace the unit.

A/C and heater raddle/vibration when fan control turned on

That vibration is caused by something lying in the fan. This causes an imbalance in the fan that gives off the vibration. You will have to remove the blower motor in order to get to the fan and clear the fan of whatever is stuck in the fan.

Heater fan broblem

You have some type of foreign material in the fan. Under the dash, on the passenger side, locate the fan motor. Remove the electical plug, and the 3 screws that holds the fan motor onto the housing; drop the fan straight down, after removing the 3 screws. Clean out the debris, and reinstall the fan. Easy to do.

The blower motor makes horrendous noises on the higher speeds. On speed 1, I don't hear any noises. There's a little rumble on 2, and the 3 and 4 shake the whole car. This is happening when the heater is...

Sounds like the bearings that are on the shaft which the fan turns on are in severe need of lubrication. You can remove the fan unit and shoot some WD40 onto the shaft and bearings.
