Default headlight/temp gauge problem

whenever i turn my headlights on the buzzer goes off,the gauge lights go dim and the temp gauge goes all the way over to the right even if the car is cold. is it a bad ground or could the dimmer switch be shorting out.

If the instruments and dash lights work fine with the headlights OFF, your problem is likely a grounding issue. Probably grounding of the headlights...check the ground paths for them.

i just checked again and it only affects the temp, but i did notice it took about 60 seconds for the needle to move and the buzzer stays on.

Do you know for sure what buzzer is going off ?
Also what ports are the leads from the headlight buzzer plugged into ?

i'll have to look. i'm not sure. i did clean all the grounds i could find, one in the back and three in the front. How many buzzers are there? Could the sending unit for the temp gauge be bad?
