I have a 2005 Honda Element EX manual. My blower stopped working recently. So far I have tried replacing the transistor, blower and I tested the wiring and everything checked out. Blower works when directly connected to battery.

Only thing left I can think of is maybe it's the controls on the dash? Any specific parts to look at or replace? I am at a loss here....

Summer is coming and I live in Florida. I wil die without AC!! I also really need my defrost for obvious reasons.....

One thing I should mention is it kicks on sometimes but is pretty much dead. Is it possible the new transistor I tried from Advance was bad? Would intermediate working rule out the transistor? I am thinking about ordering a new oem one.

When the transistor is connected I'm getting around 12 volts to the blower....

 

Are you getting 12v or "around" 12v to the motor? All full speed.

If you are getting a supply then I would look at your earth for the blower motor.

 

It was a little over 12, like 12.3

 

Look at earth? What do you mean?

 

Well I found a used and guaranteed working climate control on eBay for cheap. Going to replace that and go from there....

 

Earth, the negative wire.

If you are getting voltage to the motor but it doesnt go then what will changing the controller do? Give the same result.

So if you have a supply is there a good earth to complete the circuit?

 

Wiring looks fine. You think I have a ground issue? If my transistor is good and blower works that leaves me to believe the controller is bad, isn't that what kicks the fan on?

 

The positive side (+) of the blower motor wiring is always hot, it just needs the negative ground (-) source through blower power transistor; the ground sources (for blower fan speed) is controlled by the heater control panel.

The blower power transistor controls the blower motor in all speeds except HIGH. The blower power transistor is controlled by the heater control panel. When the control panel requests HIGH blower speed, the blower power transistor grounds the blower motor
which connects it directly to ground, making the blower run at high speed.

Issue can be due to faulty replacement blower power transistor, heater control panel, or wiring.

Try this:

1. Locate the blower power transistor under the passenger dash.
2. Unplug the electrical connector to the transistor unit.
3. Attach a jumper wire (short piece of wire) from the Blue/Black wire cavity to the Black wire cavity on the unplugged electrical connector. Leave the connector unplugged.
4. Turn the ignition ON.

Does the blower motor run at high speed?

 

Thank you, I will try this asap and post results

 

Did not turn on. Blower is not working at all

 

Then try this next:

1. Do the same thing test; but, this time use a longer piece of spare wire and connect one end to the Blu/Blk wire terminal cavity (Blue wire with black stripe) and the other end of the spare wire to ground on the car's chassis (such as an unpainted bolt, etc.).

2. Turn ignition ON, does the fan run?

If it runs this way, the blower ground wire or connection is faulty.

 

Nope. Tried multiple grounding spots too. Fan did not kick on

 

If the blower motor is good, then you have to check the power (+) again.

Check under-hood Fuse No. 12 (40A) and under-dash Fuse No. 14 (10A). If both fuses are good, then check if there is power (+) on the Blu/Wht wire for the blower motor, with the ignition in ON.

 

Fuses are good. With the connector plugged into the transistor I get 12.38 volts. Unplugged I get 0 and I'm assuming unplugged means no ground.

 

If there is power (+) to the blower motor, the motor should have ran when you grounded the Blu/Blk wire terminal that goes directly to the blower motor.

The blower motor 2P connector has a Blu/Wht wire for power (+) and a Blu/Blk wire for ground (-).

One end of the Blu/Blk wire at the power transistor connector harness goes directly to the blower motor to supply the ground (-).



This time, unplug the 2P blower motor connector, with the spare piece of wire stick it into the Blu/Blk terminal cavity, ground the other end, and plug it back into the motor. With the ignition ON, does it run?

If it runs, the issue is probably the Blu/Blk wire that goes from the power transistor to the blower motor.

 

I tried that and even ran wires from the battery again and the fan didn't do anything until I disconnected the power and it briefly kicked on for a sec. Starting to think the blower has slowly been dying and now it's pretty much dead... Maybe there's a lose connection in the blower itself? I'm lost. Going to remove it again and try to connect it directly to the battery and see if it kicks on. Maybe it is the blower itself....?

 

The blower should have ran with both power (+) and ground (-). Motor may be bad.

 

I know it's weird... It ran when I removed it originally. Not sure why it's not running now. I'm done for tonight but I'll get back at it tomorrow hopefully

 

I've checked the fuses but I haven't checked the relay. Any suggestions on how to test it?

 

If there is power at the Blu/Wht wire at the blower motor, the fuses and the relay are okay.

 

The last few days my blower has been turning on a minute or so after driving. I can hear the motor too. This is weird.....
