Guys, I need your wise words of advice before I start pulling things out at random to see what's wrong. My blower motor stopped working about 3 years ago now, no hot air or cold. My first thought was the fuse, checked and seems fine. I managed to obtain another blower motor from breakers, replaced and still doesn't work. I took my old one and checked it by running the leads to the batt, it worked >:(
So, I know it's not the motor itself, there seems to be power getting the the controls, I can hear the servos switching vents when I press the buttons.
The local breakers have an Omega in their yard, the last time I saw it the blower motor and resistor were still intact.
My question is this, is there anyway to narrow down the fault before I start pulling things out and replacing them all one by one :-?
-
cannot remember if there is a low volt relay to high volt power to the motor, think there is cannot remember but think it in fuse box under stering wheel or could be the the set in the back of the glove box.... been a long time..
-
Must be in the Fuse Box, don't have a glove box at the moment lol
-
What fuse did you check, the green maxi one top L/H of cabin fusebox?
-
Yea, 30amp F33 slot IIRC. Fuse was intact.
-
Possibly resistor packed up then
-
Was thinking that. Oh well, another thing to add to the breakers list then. Thanks Rob
-
Like for like. CC resistors are different to standard AC
-
Noted
-
look for this relay GM 90 459 640 its red/orange, Heater fan motor relay. its 40amp.. well blower relay.... :y will be in fuse box or around there.
-
Probably a silly question, but how do you go about getting the resistor out and is it easy?
-
Read the Haynes manual but be very careful I managed to snap both plastic securing lugs off ,it was very cold at the time, this is a disaster as there is then nothing to hold the resister in place
-
Does it just slide out? Had a quick go on it but it seems to only move on one side. Moved the securing lugs to one side but the resistor didn't seem to want to shift.
-
Mine on 2.6 facelift just pulled out after lugs were out of way.
-
sorry getting confused it was on my P reg 2.5 that I changed the hedgehog not the 2.6 but I would have thought that it was the same.

Not managed to find one at breakers yet, will try flebay. Couple of questions though. I've seen new ones listed on some websites, the "Hedgehog" style one.

But the one I removed doesn't have the pins like a hedgehog, it's got fins instead. 4 long 1 short. Was this just a design change at some point or are they different for a reason?
Also, when I removed the plug on top it had 5 wires going into it, but the unit only has 4 points to connect to. Think the 5th one was a red wire. Any idea why this is?
Thanks

Two types, "pins" for climate control. "Fins" for standard aircon

No picture then Rob? ::) ::) ::)
;D ;D ;D

Only the CC type resistor, never come across the poverty spec one ;D

Odd, part number on the one I've removed comes up with the "pins" type, and I was certain I had climate control.

What is it :question
-
Part number is
GM 90512510
Siemens 539.9960.010
This is the same as my console, taken from the "Climate bulb renewal (Prefacelift)". hope it's ok the link a pic from another thread.

.... and I was certain I had climate control.
if your is as per your linked picture, then you have Climate Control :y

The only difference is I've got a little cubby hole next to the radio instead of whatever is in that pic. Other than that the controls are all the same

Got two here part #`s both 90566802. Made by "Alcatel" not Siemens

:-?
I'd assume then that GM changed it's supplier at some point, which would have changed the GM part number then.
Ebay listing lists both part numbers

Anyone able to confirm that 90566802 simply replaces 90512510?
-
If it was the resistor at fault then the motor would still work on max speed setting

Ok, I'm confused (which isn't hard tbh)
As far as I know the motor works fine, put it across the batt and it spins up. So if it's not the motor, nor the fuse and not the resistor (as it didn't work at any speed) then any ideas as to what it could be?
-
Actualy, scratch that, should have read the full thread as you have climate.
As a quick test, can you connect the two large connectors on the plug that connects to the speed controller together....the motor should then run.
And I have seen the electronic speed controlelrs with both fins and pins. :y

Sorry, you've lost me :-/
-
Pull the connector off the speed controller module.
You will see some small connetors in the multi plug and two large ones. The large ones are the pos supply and the output to the fan. By joing the two large ones together you are effectively bypassing the controller and should get full motor speed.
-
Ok, this is where I make myself look like a complete idiot. The speed controller module is where?
Feel free to point and laugh now ::)

The one you took out, the one with fins. AKA resistor or hedgehog ::) ;D :y

Ah, now I see.
All I've got on the resistor is 2 single connections going to the motor itself ( a + and - ) and 1 plug with 5 wires going back up into the dash via another connector on the side of the plastic motor housing cowl, if that makes any sense at all :-/

The two connectors in the plug that marry up with two connectors on the resistor need to be bridged which in effect bypasses the resistor. If the blower motor then works, it`s the resistor that`s donald
-
Sorry, read it wrong to start with. Doh!
So what I want to do is link these 2
(http://img535.imageshack.us/img535/2687/dsc00275copy.jpg)
With these?

Sorry but the pics came out a bit small lol
Tried getting the connector out on the second picture, but she won't budge.
-
Right, managed to connect the wires together. Linked one wire and then just tapped the other to make the connection, slight spark and the motor span round. So looks like it is the resistor
Only concern was this all happened with the ignition off. I'm assuming I've got an open circuit somewhere then, or should it have happened like that?
-
IIRC there`s a permanent live supply.
If you need a replacement "hedgehog" as said got two known good ones
-
PM'd
So I shouldn't worry about the fact the ignition was off then?
