Finally got around to looking at my Ac and heat as they don't work. air blows out but it doesn't warm up in the winter or cool down in the summer. when i was looking at it the compressor wasn't starting up. any ideas on what it could be?

 

as far as the a/c turn it on in the vehicle and jump the low pressure switch with a test lead of paper clip depending what you have. there will be a couple switches, i am not sure the location on your vehicle just jump all of them seperatly until compressor kicks on. if it kicks on charge the a/c, if it doesnt kick on check fuse, power and ground. as far as the heat. take temp readings on both heater hoses with an infrared temp gauge or similar. make sure they are close in temp, if they arent backflush the heater core. if ok check mode door actuation.
