... would hate to be the first on this one .... 1st time poster
Have a '94 SSEi with 195,000km (Canadian eh?) and the HUD doesn't come up at all (checked dimmer & positional sliders). I read the previous posts and checked fuse 5A but it looks fine. In my previous check I needed to replace 9E (rear window defog) which was blown, but it didn't help.
I came across a HUD write-up that shows a HUD wiring diagram (courtesy of GM) that shows the fuse that protects the system. The diagram shows a wire from the HUD control module and a label with Fuse 20, 10A and an arrow to IGN.
Another diagram shows a symptom flow chart from the Bonneville '94 service manual to aid diagnosis which makes me think they are related.
I'm not capable of doing the probes of the HUD control module it suggests, but was wondering if there is another fuse either under dash or even in-line that I could check before going to the shop.
Any thoughts appreciated. Thanks.
