Did you ever figure out the part number or spline count? I’m in the same boat as you, it’s my only car so don’t want to take it apart without having a replacement in hand.

Right now I totally bypassed the heater core so it's running fine, but I was hoping to get some heat in the truck. Sounds like it may not be worth the trouble though. I was hoping with some rubber insulation I could stick this one into the box and it'd work well enough

I know heater cores are already covered on multiple threads, but I couldn't find an answer to the following question. Feel free to point me towards another thread if it's already been covered. But, will a 1983 720 heater core work in a 1985 720? I have the 1985 720 before they switched body styles in the later half of the year. I was able to get an all metal 1983 heater core, but I believe the one in my truck has plastic ends. Also, the angling of the metal where the hoses fits on looks slightly different, but the core itself appears to be the same dimensions. Before taking apart my whole dash I was hoping to get an answer on whether or not it's worth a try to use the 1983 in my 1985. Here's a photo of the 1983 core I have for reference. https://imgur.com/QFN7D2d

Amazing, thank you for answering! I couldn't figure out what to look up but this is exactly what I need

I know this topic is old, and most people don't like the oversized truck mirrors, but I'm wondering what the process of installing the bigger mirrors is like. Has anyone done this? It seems like most people go the opposite way, replacing the big metal mirrors with the small plastic ones. I'm sick of my small plastic ones since I'm too tall to properly see out of my passenger mirror - I can never get it adjusted correctly as it won't fully go up. To install, I know I would need to drill some holes in my door which is why I'm a bit hesitant. But once the holes are there, what else do I need so the screws on the new mirror will fasten in? For reference, this is my truck with the smaller mirrors I'm talking about: https://imgur.com/a/VAdJUF0 It wouldn't let me post the image for some reason I'm looking to put mirrors in like this:

This might be too late, but I'm dealing with this right in CA too - I just found a link to an australian site that I ordered from. 68.00 after shipping, which doesn't seem too pricey: https://abouttimespares.com.au/TimeSpares/ShowParts/32728/Nissan-Stanza-1986-EGR-valve-nos---genuine They're the only place I could find that had the part in stock

That's what I was afraid of haha, I just replaced my stereo and had all of that stuff out. It was a pain to get everything back in so I'll live with 3 speeds for a bit until I have to go back in there for another reason

Where is the switch located? Near the blower motor or behind the climate control?

Thanks for the replies. @datzenmike i put in the new resistor but the AC shuts off when I move the lever to the 4th speed, which must be what you were saying initially, that 3 is somehow the high setting - which may go with charlie69's point directly above. @Charlie69 if I understand correctly, you think the blower motor itself won’t go to the 4th speed? That some just do 3 speeds? I've seen climate controls with just the three speeds, so I wonder if I accidentally got a replacement blower motor out of a truck that only had three speeds. Weird that my old one only did three speeds too, but for all I know, that might not have been the original either. If this is the maximum this blower motor can do, I'll just live with it I guess. For reference, here’s what my climate control looks like:

Is there any way to tell by looking at a resistor if it will blow three or four speeds? The part description doesn't seem to have that info. This is the one I bought: https://www.nissanpartsdeal.com/parts/nissan-resistor-heatr~27150-62w20.html I also have the white resistor below that came with the used blower motor, but it only blows 2 speeds. It seems that all of the aftermarket ones for a 1985 are out of stock, but would one from a 1986 fit?

Got a new (used) blower motor, which is much quieter, and a brand new blower motor resistor from a Nissan dealership but it’s still only blowing 3 out of 4 speeds. It won’t blow on high. I changed out the relay and fuse too, but no luck. Any ideas how I can get it to blow on the 4th speed?

Oh ok, from the diagram in the Haynes manual it looked like there was a tube coming out, wasn’t sure what that was for when I saw it

Thanks for the reply. I was thinking of doing that through eBay, just hard to tell how well the new (used) one will work until I install it. On the other hand, reading reviews of the aftermarket ones sounds bleak so a used one may be the best option When replacing and removing the tube that attaches, will that leak Freon when it’s taken apart?

Anyone out there have an opinion on the best after market brand blower motor for a 1985 Nissan 720? I want one that fits and hopefully is a little bit quieter than the chirping original I have now. I've been searching high and low but can't find a genuine Nissan one. Also, with the aftermarket, do they still need the blower motor resistor switch to control the speeds of the fan or is that built into it now? My Haynes manual says the blower motor resistor switch was no longer there in 1986 models, so I'm wondering if this is true for newer blower motors in general. My speed 4 has never worked, but I figure if I'm doing the blower motor I might as well do it right. Thanks!

I know this thread is old, but does anyone know the inside diameter of the filler ventilation hose for the 720 fuel tank shown in @wayno'spicture above? Mine is leaking like crazy
