Driver's side high beam on my 2001 Saab CV won't work. Passenger side is okay. This was an intermittent problem for a while, and now has gone permanent. I've replaced the bulb. I've check the 10A fuses under the hood; and swapped the high beam relays. The only one I haven't swapped around is the orange light control relay. Think this is the culprit, or am I missing something else to check? Thanks in advance!

Might as well check the orange headlight control unit first, as it is an extremely common issue, and will only take you 20 minutes. Here is a step by step tutorial with pictures to examine and repair it. The tutorial is from a 1995 900 but is fully applicable to your car.

This is probably a problem with the orange headlight relay under the hood in the relay black box. Take the relay out and clean contacts and put back in. If does not fix, try a new relay or swap with another 9-5 to troubleshoot.
