Heater Problems

[Wainzor]

I have a prob with the heaters in my car,

First of all the they stopped blowing altogether, now they blow constantly unless I remove the blowers fuse on the car also the heating control won't change anything, other than the heat temperature so when the fuse is in it blows on its fastest setting, anyone have any ideas what it may be?

Cheers

Sounds like 1 of 2 things....1, the hedgehog resistor needs replacing or 2. The digital Climate control unit needs replacing (or the resistor inside it)...or both !!

If you havent got a digital climate control unit then its more than likely to be the hedgehog. If you HAVE got the climate unit then you can just replace the resistor inside it,they are prone to causing this problem.You can buy them plus the instructions from ebay and are easy to do,ive done mine before.

Kool man cheers for the help dude, much appreciated :)

Cheers dude was the resistor got it sorted today, but found a number of other issues unfortunately and now need to replace the n/s lower arm, oh well cars will be cars, thanks again dude

Which resistor,I named 2,lol

Which resistor,I named 2,lol

Hedgehog resistor, just got more probs to sort though, sorted the abs and traction lights aswell but need a few wheel bearings a front lower arm aswell and all alloys to be matching lol on top of that I have worked out that I need roughly about 2500 to fix my mrs skyline aswell, so not a fun time for cars at the moment :( but oh well I still love em lol.

[Snypa-D]

Lower front arms are pretty easy but id advise that you do both together if poss,and def change the drop links and 100% put poly bushes on the rear control arm of the wishbones

[Wainzor]

Cheers dude I am cracking on with it all over next couple of weeks, by the way dude have you had yours remapped?

[Snypa-D]

Certainly have :)

[Wainzor]

Was it worth it and do you get better fuel consumption from it?

[Snypa-D]

nope dont get better fuel consumption,but get a poo load more power for the same consumption so Im down with that :)

[Wainzor]

Lol I can live with that for the same, it doesn't matter as long as it doesn't get worse :) cheers for the info and help dude

[Snypa-D]

No worries,need anything else gimme a holla

Hi guys, just stumbled upon this thread and wondering if i got got same heater problem.

Put car away in garage last night and it was working fine.

Came to the car today and the blower started really slowly, then stopped and is now not working at all. All the controls on the digital display seem ok. You can hear the flaps moving behind the dash as you adjust the temp and settings from floor to screen etc. Just no fan.

There seems to be a consensus that it is the "hedgehog" that is the lilkely cullprit. Does this sound likely and were is it on a 318i E36?

Cheers in advance.

John.

................It could however also be the fan/motor itself !!

[mustang_john]

How can i find out which it is without buying replacments for both? Is the blower easy to get at?

[Snypa-D]

Yeah its underneath the scuttle panel,just take it out and attach it directly to the battery (or just run some wires to it without taking it out),if it comes on then itll be one of the others :)

[mustang_john]

Cheers, will take a nosey tomorrow. Thanks.

[mustang_john]

Right, here goes.

Took the scuttle cowel off and had a nosey around. I could not see any wires to unplug, nor could i work out how to remove the wiring and trunking box that spans the bulkhead. So I was not able to test the motor, but......

Whilst the covers were off, I turned on the ignition to make the flaps on the sides of the blower retract whilst in air-recirculate mode. As soon as i hit position 3 on the ignition, the blower sprang to life!

The controls seemed back to normal. So i put everything back together again and went out shopping. All the while the blower worked.

Coming back to the car after about an hour and half, and the blower had failed again. Within half a mile it started up and worked till i got home.

I have read on another forum that the hedgehog is suseptible to cold. Being that we've had a cold snap, is this just a coincedence?

I really can't afford to start shelling out for parts willy nilly and would appreciate as much help as i can get.

Thanks.

[Snypa-D]

Sounds likely its the hedgehog !! You can get them 2nd hand for cheap enough,give my BMW parts man Paul a ring on 07891 00 36 36, tell him I sent you and he'll sort you out no probs :)

[mustang_john]

Cheers, had a quick nosey to make sure that i actually have a hedgehog, yes it's there, seems easy enough to replace. Just need to get xmas out the way the get one.

Thanks again,

John.
