My fans won’t kick on when my 95 Monte Carlo gets up to temp

So is your question about your ac system or your engine cooling fans.?? If your ac compressor isn't engaging the first thing is have someone turn the ac setting ON and see if the compressor spins if it DOESN'T then most likely your compressor seized up which in that case you have to replace the entire ac compressor if it DOES spin then you can try going to any auto parts store and buy the correct ac recharge in little cans or take it to a shop and have it charge. If it's your cooling fans not kicking on at temp then it could be a blown fuse/relay or a bad fan switch find your fan fuse n see if it's blown if not swap the relay with one you KNOW works see if it helps if not I would suggest buying a new fan switch and changing that..hope this helps, good luck
