Wizards hate, or are leery of, warlocks because whenever one shows up, there might be some very nasty entity - devil, fae lord, sorcerer king, star spawn - sniffing around nearby. Even if good-aligned, warlocks seek out trouble and bring trouble with them.
At least, that's what the wizards will tell you. The warlocks will say that they can handle their perilous patrons, and that truly valuable knowledge is worth a bit of danger to obtain.
Any DM can declare that wizards and warlocks are best of chums or regard each other neutrally, end of story. But I find it more rewarding to think of potential tensions between them, and modify my campaign world accordingly.
