anyone ever did this little trick befor?

well heres the deal, my car door was frozen and i had read in the past that some of you have broken your door handles tring to open it. so being the genious i am, i poored some piping hot water on the door to melt all the ice, but like the idiot i am, i went and put the bucket back and the hot water now has become ice on my door

so i ended up breaking my door handle, heres my question

i got 2 new door handles from ebay, all metal, real nice for like 18 bux, and i can steal some rivets from work, thats no problem either, but could is be something else that i broke!? i just got the handles in today and im going to fix them this weekend, is there anything else inside that i could have broken? like any cables or god knows what, i never ventured behind my door panels befor, am i in for a bigger surprise when i try to put these door handles in!?
