Could not hear the fuel pump.

Accessories that worked
Starter turned over fine Radio
power antenna
Power mirrors
visor mirror lights

Turn Headlight switch far right and Dash blacks out and it gives you a gear box code of 0705


Believe me this was a Hard one to Trouble shoot.


The ignition switch had 12v going in and 9v coming out of the Electrical side. Causing severe drain and intermittent problems.


Ignition switch problems are common issues on Saab. What typically happens is that the

electrical portion of the ignition switch fails which results in issues such as no start, no

dash lights, no warning lights etc When you turn the ignition switch the dash lights for

all the gauges should immediately turn on. If they do not then that is a good indication

that your ignition switch should be replaced.

I hope this helps someone...
It baffled me for awhile

This is a good diagnostic procedure.. knowing what works and what does not... and why..

A possibility for a sticky.. :cheesy:

I believe the ignition switch was replaced in my car at around 100K by the PO. I think the dealer just made a good guess..

12 volts in and 9 out is a very good indicator of bad contacts in the switch..
