In this episode, I restore the heater/air con unit from the E30 325i Sport. This is something I've been putting off because of how little I knew about it. I didn't know if it was going to easily dismantle, or if it was even possible. Some things aren't meant to be taken apart once they're made, but it turned out this was not one of those things. I managed to completely dismantle every single part and see to it that they went back in looking brand new.
This unit worked as it should when it was in the car. No leaks, no blower issues, and good heat. The only thing is, over the time it's been out I've lost a few pieces, including the correct resistor that sits just under the motor. I have that on order along with a large list of parts that either went missing during this restoration or before. Obviously, due to the lockdown, parts are taking a very long time to arrive, I wanted to get an episode out so I'll deal with those small parts later and update you on my Instagram. Links the bottom of this description.
Most of the tank was in great condition and didn't need touching. But as I was already painting the edges I thought a few more coats of paint wouldn't hurt.
Thanks for watching! Subscribe with the bell on to see this car back to the factory condition.

  • Hey guys, thanks for watching and thanks for all of the advice. I've decided I'm going to change both heat exchangers (the heater core and evaporator) for brand new ones and also buy a new blower motor to go with the new motor clip that's on the way. I could have waited for all of those parts to arrive, but in the current climate, it would have delayed the video for weeks. I'll make a little video for Instagram when all of the new parts arrive. Follow @restoreitytchannel to see that when it happens. Thanks for all the lovely comments! Stay safe everyone.

    • That looks like a retrofit Air Conditioning system, ,possibly Diavia, that is what we used to fit at the dealer thirty years ago, some of them had their own resistor that fitted in replacement of the original. Great restoration attention to detail is phenomenal.

  • @14:45 i guess one must drill out those rivets to be able to remove the whole HVAC harness? Someone gutted the harness in my E30, i need to remove it and follow the electrical plan(s) to re-do the connections correctly. That small harness, that goes up to the resistor plug and the blower is "stuck", was wondering how to remove it. So even if the HVAC is removed from the car (big job) do i need to seperate the housing?

  • You sir, are exceptional! Unquestionably I do not have the patience but I truly wish I could find someone in the states that would attempt some of these restorations with your attention to detail and patience (probably said person isn’t even in existence). I have an ‘85 325e that has been in my family since ‘88 (2nd owner, 90k miles manual trans) and I drive it from time to time but needs a good amount of stuff. This being step one, the A/C and heat, planning on restoring the rest as well with all original and factory parts to bring it back to its former glory but in the states it’s next to impossible to find parts.

  • Blue butt crimp connectors at 40:13 on the wire loom, why? Why would you go through so much trouble with an insanely anal and meticulous restoratin, and then throw on a kind of fix that is used in residential light switches? Should have been a proper splice with solder and heat shrink.

  • Only thing I would have recommended here is cleaning up what use to be a plastic “white” piece by dunking it in hydrogen peroxide and give it some UV light. Would be like new in about 24 hours

  • Ah you beat me to mine for my Z3. I chose to use super high temperature range silicone foam/rubber from mc master carr with high temp range pressure sensitive adhesive. I had zero desire to do this job again as all urethane foams tend to fall apart after a few years under severe conditions. Great job though, I started mine in 2018 and should be done this week lol

  • I just recently started to figure out, why the recirculation flaps (motor controlled on my e30) were not activating. After spending 3 days following the wires, checking numerous schematics and what not, yeah...someone just gutted the entire relay to motor flap area completely. There is splice S250 and S261 that have been "modified" by someone. I ordered correct colour coded wires, in the correct thickness and shall start re-doing this....i feel your pain with regards to someone messing around.

  • if you want to bleach the dingy plastics try high concentration hydrogen peroxide and heat. there are several ‘retrobright’ tutorials on youtube by people who restore old computer components. i tried it on stained plastic parts from old musical gear and it worked very well. the hydrogen peroxide comes in liquid or paste and can be found at beauty supply stores anywhere.
