First of all, check to see if you have enough water/antifreeze in the radiator. A low water level will create your problem. After that, your thermostat could be sticking. Locate the biggest black hose coming out the top of your radiator and follow it to where it goes into the engine block. The 'housing' that connects the hose to the motor is where the thermostat is located. Remove the 4 nuts around this housing and remove the thermostat. It has a flange in the middle with a coiled spring going through the middle. You can pick a new one up at your local parts store, AutoZone, or Napa for less than $10. 140 degree F type of thermostat will be sufficient.

SOURCE: A/C unit fan is nolonger blowing air.

Either a bad blower motor or blower motor resistor. If the air is coming from the defroster only, check for a disconnected or broken vacuum line under the hood by the passenger firewall.

GM uses vaccum to operate the blend doors on their heating and air conditioning systems. There is either a cracked hard plastic line or a cracked, unplugged vaccum line somewhere. If you have done any work to the vehicle latelt I would start by looking there first.

SOURCE: no air or heat blowing from vents

Are you sure the controls you bought is good? Only a few things it can be. Control panel, Blower fan, and fuse. One of those are the problem. Cauld use a jumper wire to send power to the fan and see if fan cmes on. If it does then the fan is indeed good, then go and check and make sure power is on both sides of the fuse. then check the panel. could be bad. Panel sends signal to turn fan on and off. Good luck if need further help let me know, i will try to help ya. I am all about saving money.

SOURCE: Heater blows cold air. Vents work fine. Used the

There is a diverter valve in the coolant lines. This is used to block the coolant from flowing to the heater core in the summer time. There are 3 types of diverter valves. Vaccum, Eletric and combination. Vaccum is the easiest to check. Usually has a plunger on the diverter and can be manually opened. Use caution when working with hot hoses. Hope this helps.

The fan stopped working for the rear AC/heat in our 2003 odyssey. Checked 40amp suqare fuse under hood and it tested ok. Is there a fuse or breaker for the rear fan motor?


The large fuse you checked is for the rear fan blower motor. The fuse you need to check is for the fan motor relays and rear mode control motor. It is fuse No. 3 (7.5A) located in the driver's under dash kick panel fuse box.

If fuse No. 3 is blown and you replace the fuse and it blows immediately, you'll have to check the five relays and the mode control motor all located near the rear A/C unit in the right aft sidewall. Most likely, the mode control doors have become jammed and that is why the fuse blows. The doors shift air from overhead vents (cool) to floor vents (heat).

If the fuse is fine, the trouble is probably with the blower motor itself or the wiring to the blower motor is broken, or there is a bad ground.

The heater just up and quit working in my 1997 Jeep Grand Cherokee with no warning whatsoever. I can feel heat coming through the vents when going down the road, but the fan isn't working on any speed....


Does the fan work on A/C? If the fan isn't blowing, check the fuse. Heat when going down the road is simply an indication that the air from outside is coming through the system. If fuse is fine, blower motor is probably out.

Air and heat not blowing air through vents


Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.

Car runs fine but when the fans are off the a/c blows warm


I assume you mean the dash vent fan? If so does it work when you have it on heat. If it works on heat but not A/C your either low on freon or the compressor has failed. If it dosen't work on either it is the squirrel cage. Could be a bad fuse or you need a blower.

No air or heat blowing from vents


if the fan is blowing this could be a problem with the climate controll switch that changes the direction of air from floor to defrost to vents, some are vacuum controlled through a vacuum operated mechanism that opens and closes a door in the vents which redirects the air to different places.
