Repair advice, someone broke our mirror cover already!

[pearl-FRF]

Hi, We just purchased our new(to us) 2015 F250 this week and walked out this morning to find that someone broke the bottom of the housing on our tow mirror.(Welcome to Baltimore, my friends) It works fine, but we are afraid of leaving it cracked open and killing our switches. Any suggestions on how to reseal the plastic housing without paying a fortune at the dealership? Anyone know what type of plastic this is, because that apparently makes a difference in the bonding material to choose. This is so frustrating!
