New ccu fan

Hi
 
Not sure if you've seen but Tore at bergville fx has launched a replacement fan for ccu units in 993 and 964.  It is $160 inc postage so cheaper than Porsche part and guaranteed for 5 years.  Anyway having fixed the aircon am turning my attention to the ccu fan as mine is making a noise which has been getting worse over time.  I know you can remove and oil old fan but hear this would be a temporary fix.  Anyway have ordered one of the new fans so will report how i get on!

    I should add i have the obd diagnostics cable from bergville and the led kit, so been impressed so far with everything i have got from Tore.  If anyone wants to borrow obd cable let me know btw!

    I'm not sure I would have paid for a new fan so readily without 1st greasing the bearings on the old fan and cleaning out the dust and gunk accumulated within the CCU after 30 years of use.

    Yes i know though having spent about £3000 on Aircon condenser seals, some part of condenser was replaced, new evaporator, one new temp sensor, new rear fan resistor, new fan relay and about 3 regassings i thought might as well do it properly!   Compared to cost of all of that which i suspect actually breached 3k, it is almost a rounding error.  Hopefully it will all work properly now. Feels like I'm playing catch up on the maintenance of the cooling.  Most of this i think was wrong when i bought the car.  New fan also has much lower current draw as a bonus.

    I fitted the new fan last weekend.  It is a lot smaller and lighter than the fan it replaces.  I’m also getting a lot more air out of the vents for the same fan setting than i was before.  I replaced it with the fan controller unit is situ, i could take old fan off from underneath the dash.   The old fan seemed okay nothing obviously wrong with it other than the noise it was making and air flow bit weak.  I’ve kept it and greased it incase i need it again, if i get time in a few months I’ll swap them back and see what difference greasing the old fan makes.

    I got the LED kit, very. Impressed.
    was thinking the fan as well, really better flow rate than before?  Like noticeable in level 1, I have it mostly there.

    Yes it was noticeable on first setting of the fan, if you dont have a problem though i would be inclined to hold off given the cost. I thought the ccu fan was making a noise and on its way out but i now think it is the right hand front blower motor that is causing the noise and likely that is starting to fail.  It sounded like it was coming from the dash but given i replaced the ccu fan it cant be that as i still have the noise!
     
    If you dont have it, the obd connector from bergville is very good, i do use that fairly often so I'd get that if you dont have it.

    Thanks 🙏 
    slight high pitched sound when on 0 sometimes, not on other settings so assumed lower speed likely to cause that intermittent
    will look into the OBD 👍

    I'd suggest to try grease on fan first, it is really quick to do if you take off fan and leave ccu unit in situ.i just half popped ccu unit out to give myself bit more room behind and it is 2 screws and one clip.
