Climate control messing around

[Kurt Adv]

So, today, my climate control decides to bugger around, and it was pretty hot, fan speed indicator indicates what it should....but no blow.....Then tonight it's working fine again....anyone else had this issue? If so, what did it take to fix it? Besides a visit to the stealers....

Is this an e46?
Check the Final Stage Resistor.

PITA to change though :nonono:

Much easier to do in an automatic though, as there's no clutch in the way...

i learnt the hard way with the FSR,the most common cause of failure is that it sits in an air channel for the feet that allows it to disipate heat but with no airflow over the FSR it overheats and fails. As a rule of thumb place the air direction downwards to your feet as well as other directions needed so the FSR keeps cool and lasts longer.

i hope this makes sense...

Yup, E46, 2002 model 330i....I'll check in the workshop manual where to find this resistor.....gonna be interesting I'm sure....

Good luck, I have an E36 318 digital control with similar issues, I don't know whose climate it's controlling, but it's not mine! Comes and goes as it feels, aircon on with no fan, etc. Will be watching closely. GOOD LUCK.

Hi there. I came across a few of the faulty E36 318 Climate Control units. It exhibited the same symptoms as you are describing above. All of those units had the same problem. It had a few dry joints on the back of the Climate Control unit's PC board. If you have any soldering skills this should be an easy fix. :thumbs::thumbs:

Seems to work fine on manual, Auto and Climate Control off, might be the brain messing around, will watch it for a few days, have a lekker bike to ride at the moment, car is standing......

Just be aware that if you leave it too long it eventually flattens your car battery, as a faulty FSR causes the fan to come on while the car is switched off.

Hence, if you leave the car standing for a day or 2 and the battery goes flat, at least you know what caused it.

You can pull the fuse on the blower motor for now to prevent battery drain until you resolve it. Like msm mentioned. it will drain your battery as the blower will run even though the keys are nowhere close to the car

Nope, fan is off if the key is off.

Bemows, R795.00, BMW, R1435.00........FFS!!! And BMW admit that these units give a lot of shit......
Anyone used the Bemow's unit? Does it last as long as the BMW unit? Bemow say they import them from Germany....

+1^

If you leave it, it will start working even when the car is off as well

Changed it, I now have an aircon again, this item has been changed before, half the screws were missing......but what a biaatch of a job......
