325i Fan/AC starts and stops

[Qamar]

Hi Guys

My friend have a 325i, 1992 model. It has done 180000 Km. Automatic. The car is in very good condation. The only problem it has developed is that when ever we start the car the Fan blower motor and the Air conditioner starts automatically. No matter how much we press the concerened nobs to switch them off. The recent development apart from this is that when we switch off the fan the fan and the AC starts, whereas when we switch it ON it goes in the OFF mode.

We have recently changed the old battery with a new one. Do you think that could be the main cause of this problem.

Any help will be highly appreciated

Thanks in advance

it's not the battery. it's the module that controls the climate. parts inside are failing. get it replaced

i second that. E36 are pretty know to have the climate control unit go bad. there are fixes out there, no one really knows how reliable. some say it works, so say it doesn´t. getting a new one from the dealer might probably be the best idea.
