1990 Corvette Headlight Problem & airbag/seatbelt light on
My recently purchased 90 Vette has a couple issues: 1. Both Headlights do not open fully, but do close. Car has only 2600 miles so I know they have not been used a lot 2. Airbag light and seatbelt light are both on (came on after service at Fred Beans Chevy after injectors replaced and horn issue resolved). Fred Beans Chevy says it has a code 26 (left frame sensor). They cleaned it however there was no corrosion. Code could not be cleared. Not sure where to go next. Time for Bryner? Do you think they are better than Fred Beans service and can solve the airbag light issue as well as the headlight issue? Thanks for any advice.

Ken, Take it to Bryner. Steve Spencer is the best!!
Headlight could be adjustment/index/micro switch issue. Steve will know. On the airbag it is probably a bad ground somewhere.
You Could also try to contact Gordon Killibrew (Former Corvette Action Center Guru). He charges for advice but he can fix the C-4's in his sleep. He was just in Carlisle-I saw his wife there today.

Info on Corvette forum regarding airbag/seatbelt light
You guys are experiencing one of the most common issues with the 90. I had the light come on several years ago due to the right sensor and just a few months ago the light came on again this time because of the left sensor.
The problem is corrosion between the frame and the sensor. Mine was very easy to fix. I just disconnected the battery, removed the two bolts holding the sensor, sanded both the sensor/frame faying surfaces, coated them with dielectric grease and reinstalled the sensor.
To turn off the light I use a special plug/switch I bought from Corvette Central (I think) for a nominal cost but there are other ways to do it.
Just make sure you disconnect the battery before you mess around with the sensors. Good luck
Yep most of the time it's the right front frame sensor that goes bad. Sometimes you can repair the problem by DISCONNECTING THE BATTERY then removing the sensor and taking a dremel tool or small grinder and removing the paint or corrosion on the frame where the sensor sits and sanding the bottom of the sensor and applying some dielectric grease to both areas then I put small star washers on the bolts (better ground) and re fastened em. Then ya gotta clear the code to turn the light off. Mid America sells the connector/button tool that hooks to your ALDL connector under the dash that will remove the code Remember sometimes cleaning the frame and sensor won't always work and the sensor must be replaced.
