Check the fuses, your owners manual will show where they are located, if this isn't the problem then you may need to replace your blower motor, a simple job in most vehicles requiring a minimal amount of tools and a little electronics knowledge

Is there a fuse that run the air condition inthe honda odyssey 2006

Hondas all have a fuse and blower relay located in the battery junction block. You can try swapping relays around if the fuse is good. Then verify the blower motor is good by disconnecting it and applying 12v directly to the motor. If this checks good, check for 12v at the blower connector while disconnected, (key on/fan on). Had a CRV in the shop a few days ago with the exact same issue, power to the motor but a weak ground signal. Replaced the blower resistor.

I have a question regarding my 2006 Dodge Stratus SXT. It appears that my air conditioning system will only work when the fan is turned up all the way. Any idea as to what might cause this?

So the fan only comes on when it's in the highest setting? If so the problem is likely your blower motor resistor. It is responsible for dropping voltage which determines the other fan speeds. The blower motor resitor is located under the passenger side of the dash near the blower motor and is readily available from most parts stores or your local dealer.

Blower fan is hitting something . Do I need to remove battery cable to work on this?

no you don`t need to disconnect the battery to work on the blower motor.just remove the motor and check the condition of the squirrel cage(not damaged) and check inside the air box for debris and clean out.make sure the noise is not the blower motor itself.

  • If the fan does not work at all on the lower speeds than the most likely problem is a bad blower motor resistor.

  • I can give you some pointers on checking if you need it.

Where is the blower motor resister on a 2005 chevy avalanche

from pictures I'm seeing, it looks like it's next to the blower. Remove the insulating panel above the passenger's feet and look up. See if it looks like the picture below:

it may not be the blower motor. it may be the blower motor control module which use to be the resistor. it's located under the pas. side. remove the black coyer , 2 scaews above the pas. foot area. then remove the blach unit that has a purple wire going to the back of the motor on the right. price about 140 dollar with tax.

Blower fan has stopped working except on high

The motor still works. A DC motor is speed controlled with a resistor. Luckily, the resistors that do this are mounted on the motor housing. See the following link. The resistor pack is quoted as costing about $10.
