Faulty Ignition Switch - Resolving Non Start Issue on Saab 9-5 (MY06)

In this video, I demonstrate how it is possible to open and clean the contact/points of the Ignition Switch found on the later Saab 9-5 (4943692).
When my Ignition Switch failed, I had a hard time finding a new replacement. Here in the UK, it was impossible to source a new item as they are no longer in production, as expected the remaining Saab stock has been sold.
I searched the UK and mainland Europe for a genuinely new item, however, I failed, I had no other choice but to look for a used item or one that was made by a 3rd party brand.
Luckily I purchased a used item from a reputable breaker from eBay who stated it had been tested before removal. On arrival, it looked dirty and I instantly regretted the purchase, the condition did not give me the confidence it would work. I gave it a clean but it still looked and felt greasy and rough, I was so annoyed as it looked old and dirty.
I had a good look at the failed unit and noticed it was not a sealed unit, the unit consisted of two halves that were held together via three clips and secured with two bronze striker pins. As seen in the video I took apart the internals were really oily due to my previous use of WD40 (MISTAKE). The were traces of dirt, plastic, food and oil which prevented the spring from touching the contacts, once I cleaned up, the spring was free to travel and make connections.

I just cleaned mine- took out, noticed the lube grease melted in the heat and coated the contacts-preventing contact-be careful taking it apart- pictures for guts- and where springs go-(2) 2 with 2 without. clean contacts with micro file or sand paper then re assemble- i removed all old grease, i even lost one of the springs(tiny) but after reassembly- and make sure you do it right- I reinstalled the switch and the atenna- and tried it out- WABAMM it works. btw it is all mechanical- becareful and reassemble correctly and it should be fine: also the covers only go on one way but the dam switch piece (rotates between off-on-run start)can be troublesome to make sure it is lined up correctly.

Hi from near London:P Just got myself a 56 plate Saab 9 5 2.0 T auto with 91k miles on it, last owner drove it the last 5 years like 2k miles a year only. I bought it off his son in law (the gentleman passed away a year ago), so it was starting with a jump start when I saw it first a week ago. When I went to pick it up same thing, started with jump start, drove 50 miles no issues, stopped for petrol near home and it wouldn’t start. Assuming it was the battery, bought a new one and started. Left it overnight and wouldn’t start in the morning but tried in the evening and it did. Today tried 3 times and started but it takes 1 or 2 seconds before it actually starts to run. When measured the new battery after the first night in the car, voltage was showing 10.6 only. I understand the ignition switch fault can eat in the battery as well as a side effect. I can’t find a new one all sold out (that should tell us something) so ordered an used one off eBay and waiting to arrive. I hope it will solve the issue then me recycle the old one and keep as spare. What symptoms you had? Do you think could be something else?

Is it turning?
If yes, it's not your Ignition Switch.
If no, it's very likely to be your Ignition Switch.
If it is turning and not firing, it is highly likely to be your Crank Position Sensor.
If it is the latter I would recommend you replace it with a renowned brand item.
The Turbo and three-way Cat causes such heat that it accelerates the lifespan.
Let me know how you get on.
Best wishes

Did it work ☺

[@the80sdude51]

Hey Pascel,
I have not tried it, however, judging by the crap I removed from the contacts and pins and I very confident the issue is resolved.

Hello,
Does the starter running with a bad ignition Switch

[@the80sdude51]

Hi,
A bad ignition switch will behave in the same manner as dead starter motor.
