When I pull the lever on the steering wheel to engage my high beams the blue light displays, but as soon as I let the lever go - the high beams go off. I cannot get the high beams to stay on. How do I fix this?

Sounds like the lever switch in the steering column broke, it's not staying clicked in the on position, and some of them are not easy to change.

Sounds like either the main beam relay is not working, or the switch itself is faulty. As it works the lights until you let go then more likely to be the relay. Some newer cars (in europe) don't have an individual relay, instead have a body computer which needs replacing and costs a lot. Hope you have a simple relay type car!
