Why does my speedo die when I turn the lights or left turn signal on?
reminds me of my buddy's POS 2000 Saab 900. The mode button is supposed to choose between MPG, trip duration, etc.
What does did it do in that shit bucket?
Zero out every gauge in the car for 20 seconds. shit was
Well ... depending on what you do
Lights on = speedo dies, alternator gauge takes a dive, temp gauge spikes, haven't paid enough attention to the gas gauge
Turn signal on = all gauges bounce ... BTW, only with the left signal, the right signal works fine.
Also, with the lights on, the high-beam indicator is on, but not very bright, yet goes off when you turn on the high-beams ... which are only the high-beam lights as well - the low-beam goes off (not supposed to)
And no dash lights ... at least not enough to see the gauges that aren't working anyway with lights on.
I noticed you weren't getting very far with this thread in the main forum
Anyways it's probably a busted relay, faulty ground, or other short somewhere in the connections for the dash. Chasing that down could be a huge PITA. Fuck electrical work in cars.
this has been true since chryslers inception lol
What year/model? Just curious.
Negative, I've had 0 electrical problems in my '74,'75, and '78 Newports, '75 Cordoba, '65 Imperial Crown, and '96 LHS
'90 Fifth Avenue, '98 Concorde, and '90 Dodge Dynasty all had (electrical) tranny problems
'93 New Yorker Salon
thinking I'll take the bulb out of the left front signal and see what happens
Almost certainly a faulty ground. When electricity can't drain to the negative battery terminal properly, it will flow backwards into every lower-voltage circuit it can. That causes all kinds of malfunctions, though there usually isn't any permanent damage. Time to tear out the dashboard and brighten all the ground conductors with a wire brush.
EDIT: '93 is pretty old for a "normal" car. I don't know how humid it gets in Washington, but I'm gonna guess you've got a good bit of corrosion on wiring contacts all over the place by now. My dad's 1995 minivan eventually got junked because of electronics problems that were keeping the transmission computer from working properly.
