Front Heater Blower

[scorch21]

Hi everyone and anyone,

Can anyone pls tell me why the blower fan (the one behind the glove box) stays on even when i have turned the controls to OFF, this is truly doing my head in, also haven`t got the drivers manual so what does the econ button mean???????? hope someone out there can put me out of my misery.

It's sounds like opposite problem to mine ;) If yours Gal have a electronic climate control as mine does, then blower is controlled by earth connection with a blower control unit. Mine was burned through, so blower itself had voltage on one pin, but no ground on other. In your case I think that the same red 3-pin control unit is faulty, but In this case it has a connection to ground, so there is no managed resistance to slow blower down, and it spins in max revs.

 

At least you have working blower, and windscreen doesn't mist up ;) Mine until I'll find this unit is out of the game :D

 

ECON is for saving fuel, it's like when you want to cool cabin down it won't engage conditioner at it's full power, so you might get a better mileage.

Well, the faulty unit, which I'm talking about isn't a very cheap thing, so better someone sort it out is it really broken (I'm calm for mine, as there was fire on connections:) ). But to get it there is no big deal. I suppose you have a car with a right side wheel (sounds funny to ask in this forum, but I'm from Lithuania). So in left passenger side, you must take out this glove compartment. No need for screws yet, just open compartment and take it out, need some force, but not to brake anything on it. So with a Philips screwdriver there will be 5 screws to take out. They are at edges under glovebox, we took out. There is a plastic rectangular loop in the center where is the last screw. At the edge of all this plastic panel, there is a plastic fixator, which you must take out with a "minus" screwdriver and take out with fingers, no big force to save it ;) So all plastic panel beneath air bags eventually easily comes out, and all "entrails" of aircon and heating/ventilation unit are opened. There you can see blower with two pin connection (Black/red and White/red cords), and a red plastic box, which I think is the cause of your problem. It has 3 pin connection (small yellow, that comes from A/C panel; 4sq.mm Black/red that comes from blower; 4sq.mm Brown which is connected to the ground). This red gadget is connected to a evaporator compartment with a Torx screw.

 

P.S. By writing this text, I think of yellow cord, that comes from A/C panel. Maybe it could be broken, so this control unit doesn't get a signal to slow down, and without control input, there is no resistance on blower's ground connection.
