I got a 1988 hatchback. Just recently when i turn on my heater full blast my brights come on very dim along, with the blue brights light in the dash . If you turn the heater off, then the brights go off.i haven't tampered with anything under the dash. Any ideas?

 

bad technology. anything electrical on these cars effects just about everything else.

Youre bone stock? nothing done to the motor or wiring?

 

found the problem. in the head light harness, theres a little **** colored box with a bunch of grounds...yea it has to be grounded to the frame. not balled up in electric tape. Thanks anyways.
