04 Ascender problem

Hello - first post here. I have an Ascender that I bought new, still runs great. However, I live in a small town and they don't handle Isuzus so thought I'd reach out to the internet.

4.2L inline 6 engine, 9 passenger, 70,000 miles.

Problem is the low beam lights occasionally go off. I switch to high beams & ok. A little nervous when it happens on the freeway. Also, holding the lever for high beams works also.

Any suggestions ? Thanks - Steve in so la

Replace the headlamp solenoid, this is a known problem with Ascenders, Trailblazers, Envoys , Rainers etc .... there was even a recall on later years . Had it replaced this year on my 08 Ascender .
