Need Help With Headlamps On 98 Firebird

[Tinee]

ok heres the deal just bought a 98 firebird and the thing is when im drivin in the day time and as soon as i hit my turn signal the head lights come up. the car was made in canada so i understand that it has drl system but i thought that would only make your runnin lights come on not the headlamps. went to dealer to see what they said and they told me it would most likely cost 160 to look at and price of a switch if that is what is bad, he said prolly lookin at 500 total. well thats alot of money for a bad switch and im not sure that he was makin much sense. hopin someone can help or give a few suggestions.

                 thanks in advance

look up firebird turn signal switch on google, see if this will pull up the diagnostics for electrical and switches ,then go from there
