I just replaced my coolant temp sensor on my 99 3.8 liter mustang, and now the AC clutch isnt functioning, so not blowing cold. What could have happened?

Just a coincidence I think. Check the AC compressor fuse and the connector to the compressor.

I checked the connector and im not sure where the fuse it to the AC compressor bc no owners manual but if not that then what could it be?

A bad compressor or low on Freon.

do you have a cheap 12volt dc test light to check power at the plug in on the ac comp.? check the low pressure safty switch also even though you werent around that area ...and WOT ac cutoff switch and ground look at bottom left side look this up.good stuff wires > www.stangnet.com/mustang- forums/threads/a-c-clutch-will-not-engage-but-air-will- blow.677889/

Could be the new sensor is wrong or defective. If the computer thinks the engine is overheating it will shut down the compressor. HTH. -Jim
