How do you repair a 1999 Jeep Grand Cherokee no air blowing heat or cold?
Check blower motor fuse Blower motor resistor pack? Fan switch? Selector switch? ---- Is the Blower Motor Working? I'm not sure if the question is that the blower motor is working and "no air is blowing thru the vents'! If the blower is working and no air is blowing thru the vents then you could have a broken Recirculation Door. That is another common heating problem with the 99/04 Jeep GC. The recirc door brakes and falls down blocking the blower which will reduce or block the air flow completely. Normally the dashboard would have to be removed to replace the broken recirculation door. See the Link below for a NO Dash Removalrecirculation door fix. ----
If a 00 Grand Am SE vent controls will not allow air to come out of the vent and the air is rerouted to the floor vents when dash vent position is selected could this be blower motor resistor?
No this wouldn't be the blower resistor. If the blower resistor was bad then the speed selection would only work in high speed mode and no other. If air will not route through the air vents then their could possibly be a bad vent door motor or vacuum diaphragm. Check those.
Why would the vents in a dodge avenger be blowing dust?
your cabin filter might be dirty
Why heat or air isn't workning?
Can you feel anything coming out of the vents. Also if you turn on the dial that controls the speed of the blower, and you dont feel anything coming out then you need a fuse or blower motor or mabe a resister for the blower motor. I would have to say that 8 out of 10 times its usually the blower motor resistor. Hope this helps
What else would stop a blower motor from changing speed 1234speed dont work?
If you only have high speed I would blame the blower speed resister. If you have no speeds and the fuse is good, I would blame the blower motor or the switch.
What would cause heat not to come out of vents when set to floor and vents?
There are heater doors on the heat blower box that direct the path of the heat. Apparently the heater door to the floor vents is stuck closed.
What would cause the blower motor on a 2002 Malibu to work only at high speed?
I would suspect the blower motor speed resister is shot.
Why would air conditionerheater fan on 95 Buick Riviera work great sometimes sometimes not at all?
Please describe in detail what the a/c heater blower is doing I.E., air blowing out of one or both vents, defroster operating or not etc. jb
How do you fix heater fan when it stops working on a 1994 Chevy s10?
If you have no blower speeds at all, first check the fuse. If the fuse is okay I would suspect the blower speed switch and its electrical plug has melted. If the switch checks okay I would suspect the blower motor is bad. If you have high speed only, I would replace the blower motor speed resistor. If you have all lower blower speeds but no high speed, replace the high speed relay.
What would cause your blower motor to work on only one speed on a 97 Chevy k1500?
If the one speed it works on is high speed, it is the blower motor speed resisitor that is bad.
Where is the high speed resister on my 2003 winstar blower motor?
It would have a high speed relay and it would be in the power distribution box under the hood. The blower speed resister is for the lower speeds only.
Why would the dash vents on your 2004 Trail Blazer not allowing air flow?
It should have nothing to do with the vents itself. More than likely it's the blower motor that's not working.
