Anyway, a few weeks ago on a hot day I got in my car and there was no air coming from the vents. To make a long story short the SAI pump shares a fuse with the cabin fan. Through some playing (and lots of fuses) I found out the SAI pump was causing the fuse to blow. I unplugged the pump in the engine bay and waited for the check engine light (CEL) to come on. It took about a week to show up with a P0410, Secondary Air Injection fault.
Today I took the battery out and removed the pump to dissect it and I think you will be interested in seeing what I found.
1. Here's the pump more or less before taking it apart:
2. Here's the air filter cover taken off. But hey, where's the air filter? What the hell...??
3. I can't get the blades the turn, wow the motor must really be fried:
4. Oh wait, what's in there??
The needle nosed pliers say...
5. Yep, the darn thing inhaled its own air filter.
I'm thinking now I should dig a little further into the SAI system and dig out the rest of the chunks of filter that must have been blown into the valves and stuff. Fun stuff. A new SAI pump runs about $200 new, and I got a quote for $135 out of a salvage yard. I'll probably buy a new one. So the moral of this story, if you've got a 2000-2003 9-5 V6 and haven't had the filter changed in there for a while, you may want to get on that. Soon.

I just bought a 2000 Saab 9-5 V6. After I bought it...I found that SAI pump was disconnected. If the pump serves little purpose...what is the potential damage if left disconnected?
Wow, man you just saved my life, I am helping my mom out by taking her 2001 Saab off her hands and I was about to give it back to her because my friend (lexus mechanic)checked it out and it had 2 error codes (410 and 420). The SAI pump is not sold ANYWHERE around here and there is no air/heat/fan which also points to the blower motor not working. Between the two problems I was looking at having to spend $1000. After reading your blog I am disconnecting the SAI pump (useless) and will be changing the fuse out to make the blower motor work. Seriously THANK YOU SO MUCH you saved this family a TON of problems... WOW.
They foreign exchange moraine Ohio wanted 1600 said throttle body failed said they have high failure rate due to sticking when depressed can u say w d 40 we did same as u did with no filter replaced left it out disconnected battery cleared engine lights n codes no worries runs fine
We believe we have 16 cents into it
Just bought used 2000 Saab 9-5 SE, runs great, has CEL code P0410, your blog helpful, mine has 107,000 miles, so probably has similar problems.
