Technical Heater motor

Is it a part just for the croma or is it the same as another car / model.

Also does the dash have to be removed to change it

 

[blueh2steve]

Oh yeh, forgot to ask, anyone got one for sale.

Elearn says take out glove locker, but just had mine done. Alex got up behind the glove locker and had the fan out in 20 mins. Before he started he said "its usually the controller" and sure enough the electronic controller under the fan had caught fire, and burnt a hole in the plastic case.

This was most likely the result of a local garage leaving off the little drain pipe from the windscreen bottom rubber seal. Have not got them to admit it though, might be difficult to prove.

The fan is about £150, the controller £90, parts are croma specific.
The result of leaving the drain off was a saturated front carpet. I didn't know this was happening until the fan stopped. The water also came above one connection above the sill which stopped the throttle operating until cleaned.

Here's what I found out previously (good news, it's a Vectra part)...

As I said in that thread, it can be done without taking the glovebox out, but it's not much fun fiddling about while standing on your head. It's also very easy to break the crappy plastic brackets that hold the foamy cover in place. If I did it again, I'd look at how much work is in taking the glovebox out (probably not very much).

Think yourself lucky...

Heater fan motors have been known to short circuit and set the cars on fire.

I have the blower out and it is fooked, the number on it is 007016m, there are a couple on fleabay under Vectra C but the number on them are 007017j, they look the same but anyone know for sure.

 

[Doofer]

I don't know the answer directly, but I'm pretty sure that there are different versions for either manual air con or automatic climate control. Could it be that the two part codes are not Croma/Vectra but manual/automatic?

I don't think climate control was that common on Vectras, so it may be harder to find one for an Eleganza or Prestigio (which have climate control).

This is only a theory - let us know what you find out.

 

[Radlet6]

Doofs you are right about the auto and manual air con, but it gets worse. The RHD and LHD models have different fans too. Here goes


LHD Manu air con fan: Part no.77363758

LHD Auto air con fan: Part no. 77363723


RHD Man air con fan: Part no. 77363774

RHD auto air con fan: Part no 77363776

I'm afraid I have more bad news. It doesn't look like it's a GM part either.

 

[keithglos]

When I said it's Croma specific I was referring to Fiat ePer parts list, the heater fan was not used on any other Fiat make. This might suggest that it was sourced from GM parts bin. just a thought.

 

[Doofer]

I'm afraid I have more bad news. It doesn't look like it's a GM part either.

Why do you say this? It must be GM - it looks exactly the same as one. I think it's actually Valeo.

E.g. Vectra manual air con version:

Vectra automatic climate control version:

http://www.ebay.co.uk/itm/vauxhall-...CarParts_SM&hash=item2a1d43392d#ht_500wt_1361

By the way, from a quick scour of ebay, the automatic one is much, much rarer than the manual one. You're alright if you've got a Dynamic.

We need photos of a Croma one to compare (hint: blueh2steve)

 

[blueh2steve]

Hope these help

 

[Doofer]

My conclusions attached as a pdf...

Keep us informed as to what you find out. Mine's a bit squeaky, so I'll have a go at cleaning/lubing it, but will be after another if I can't get anywhere.

The price of that ebay item is a bit shocking, but they should be cheaper elsewhere. I just used that one as they had good photos.

 

[blueh2steve]

Got a motor off Ebay for £55 inc delivery, fitted it yesterday and all is well. Was listed as off a Vectra C with climate control.

 

[evo-number-one]

Great result Steve!

Did you spot what the Valeo reference/part number was for the Vectra one you have fitted?

If you can, would be good if you could do a step by step "How to" re removal/refitting/tools required/estimated job time etc for future reference.

FITS VECTRA C YEAR - 2002 - 2009



Sorry did not get any numbers off it, took about an hour to get out, no special tools, star bolts to take glove box out and disconnected the air bags inside door jamb.Also had to take off the side trim near gearbox to make access easier. About 10 mins to put back as i knew where the bolts were situated. All in all a bit fiddly but quite easy.

It's a fiddly bugger, especially a couple of bolts towards the front of the footwell - where the floor comes up to meet it.

I ended up using a torx bit with a 1/4" spanner for one or two, as there's no space for a screwdriver.

All this is while standing on your head in the passenger footwell.
