Smoked out

After spending an hour scrubbing off the moss on the outside, fixing the gauge cluster, and trying to clean the dash I decided it was time for a freeway speed test to see how highway worthy the car was. I was considering taking it to an autocross; not to race, but just for the road trip.

Got it out on the freeway towards the end of the day, it was threatening rain and starting to get dark, but I wasn't going to be out for long anyway. Felt fine at 30-40 mph, but developed a pretty nasty shimmy over 50-60. As I understand it, bad front suspension bushings on this car are the likely suspect. Between that and a bad rear subframe bushing that clunks on/off load, I decided that was the last time it sees those speeds until I get the suspension fixed on it.

On the way back in I noticed a burning smell... didn't think much of it at first, but it progressively got worse. The combination of smoke filling the cabin, the windshield starting to fog up and the rain obscuring everything came on pretty quick to the point where I had to pull it over and get out of the car. Running through my head was the possibility I screwed something up in the dash and that the dash was about to be on fire. When I first bought the car I had the foresight to buy a fire extinguisher for it, but thankfully it never came to that!

After airing the car out and limping it home in the rain with the windows open (smoke was still coming in, but from who knows where), I'm able to get it back in the garage. Figuring putting a smoking car in a garage full of bikes and tools is not a wise idea , I start poking around to find the problem to make sure it doesn't set everything on fire. Smoke was still coming from the hood vents. Turns out in cleaning the dash I turned the blower speed all the way up, and the fan blower motor was seized. Somehow no fuses were blown, but it was dumping enough current into the blower to start melting the plastics, pushing all the smoke into the cabin.

Deciding I didn't want to see this happen again, I opted for a new fan instead of a junk yard find.
