Electrical problem
1987 Mazda b2200 4 cyl Two Wheel Drive Manual ~90000 miles
Note: here's what I posted almost a month ago to a mazda site in Australia, having had no luck with any site in the US. No luck there either, no answer - nothing... Then I found you and am trying again...
(Newbie here, just signed in today, located in the US (Virginia), and can't seem to find any help here - all clubs I've tried are mainly into rotary cars or later models than mine - '87 b2200 pickup. So I'm hoping someone down there has been interested in keeping an older Mazda pickup going, and in the process, learned some of it's hidden tricks that I can't seem to find the what's and where fore’s to fix.) Thanks in advance, eh! -Bob-
So, I'd like to find where Mazda has hidden what I suppose are some resistors to regulate the fan speed for the heater/air venting system. When I got this truck (ok, little truck) the heater fan didn't work. As this winter started to get cold enough to fog the windows (inside) I finally pulled the fan motor, unstuck the bearings, lubricated the bearings, reseated the lower bearing and reassembled the unit. Motor now works fine, but only on high speed, so I'm assuming that when the motor was stuck, turning on the switch (leaving on the switch) caused nothing to appear to happen but would likely burn out the resistor network used to regulate the speed (if that's the way they built it).
Also, after fixing the heater fan (somewhat) my windshield wiper that had been such a delight is now no fun at all. By that I mean, previously the switch (stalk) moved vertically would do three different things - off, ~5 sec delay, and full on. Now it does two different things - off, full on, and full on. Hence, something changed, but what? No wiring diagram I can find shows any hint of where a delay network might be hiding. Any help as to what and where?
