Description of your Car(s):
Car 1: 1991 505 SW8 2.2i automatic--my work car. I'm on the road a lot.
With the rear seats removed, it has lots of room for tools etc. plus
ladders on a Thule rack. Much better than rattling around in an old
pickup. Also helps to promote my offbeat yet hip image. I'd like to
find a SW8 trailer hitch (Peugeot accessory #2.A3).
Car 2: 1992 (yes) 405 DL sedan automatic, ex-Peugeot factory reps car,
now my wife's commuter car. A real lady (the car).
How long you've owned Peugeots: Only two or three years.
Other cars you own: None that run.
Professional automotive experience, particularly Peugeot:
Just your basic shade tree mechanic.
Current project:
Trying to figure out replacements for the pair of transistors in the
405's blower control module. One is shorted, the other is still good.
The TO-3 case is marked with a Motorola logo, but the numbers are OEM.
The schematic in my 505 shop manual says it's a PNP biased through a
series of resistors selected by the knob on the climate control module.
It should be the same idea in the 405, except the 405 module has a pair
of transistors which suggests a Darlington circuit.
I'm assuming an Ic (max collector current) of 15A (measured blower
current when connected straight to 12 vdc) and the highest Vceo (max
collector-emitter voltage) I can get to resist voltage transients (which
is probably why the bad transistor shorted). However, Beta (current
amplification factor, aka Hfe) is unknown. Any ideas out there? Hello?
In the meantime, to keep the wife happy, I wired the blower through an
on/off switch and 1 ohm of resistance to cut blower speed. It's crude,
but it works.
