Back in a GL


Recommended Posts

First joined this forum 20 years ago when I had an 84 hatch that I had bought sitting in a field while I was in high school. At the time, I had a 91 Legacy. Drove that till it blew up and then picked up an 83 Brat that I found for sale on here and picked up another 83 for parts. Had a 2000 RS coupe in college, then a 95 Outback beater. Sold the RS and got an 05 STi, sold it in 2016 and got back into an 04 WRX in 2022. Picked up this 84 GL 2 weeks ago as if I needed another project but I am not poor on vehicles - also have a 2019 Tundra and 2015 Rav4.

This thing was in surprisingly good shape for being an east TN car. With that, it does have its issues. I have on my work bench a new rear wheel bearing to install, hatch struts, will need a radiator as I see it dripping. I am also trying to nail down why the blower isn't working. I pulled the fan resistor switch last night and it showed continuity but I need to see exactly what ohm values it's supposed to have. Nothing like reading 20+ year old USMB posts. 

We still like pics on here?

Is that a 2wd?  Replace the wheel bearing by replacing the rear axle.   :)

Blower circuit is mildly annoying.  If it won't work at all, it's not the resistor - the resistor isn't used on high speed.  There's a hidden glass fuse and a round relay tucked up in the dash somewhere to the left of the steering column iirc.  The relay is turned on by one of the accessory fuses and a ground wire to some screw somewhere that I don't remember, and the power to the hidden fuse comes straight off the fusible link.  This provides positive to the blower motor.  Negative to the blower motor is through the resistors (except on high) and the switch in the dash.  Pop the plug to the blower motor and get a test light out, see if you're missing positive or ground.  If you have no positive, then dig under the dash for the relay and hidden fuse.  If you're missing ground, then check the speed switch in the dash and its ground.  If you have both, might need brushes in the motor.  Just to say it again, **hidden fuse**.  It's a clearish/white plastic glass fuse holder just randomly dangling off the harness tucked up in the dash and not accessible, and this is the fuse that powers the blower.

The only available radiators are aluminum these days.  If you use one, you must install a reservoir like a newer car has.  From what I can tell, running them without a reservoir, with an air bubble in the top like these cars normally run with, causes them to instantly crack due to thermal stress as the air bubble moves around.

Thanks man, I really appreciate it! Yes, it's 2WD 5MT. 

 

I'm going on vacation tomorrow for a week so I'm going to have to tackle it when I get back. I wanted to do more testing before I dropped ~$100 on one of those resistors and the one I have now definitely looks to have been replaced. 

 

Good call on the radiator.
