Hello everyone, I'm here as a last resort really. I tried looking things up on this forum and on youtube. Whatever to get a idea of what I can do to fix my situation.

My 2010 CX9 Grand Touring out of no where stopped blowing cold air in the summer in the front of the vehicle. The back would still blow ac and heat. Then after 1 week that went out as well.

After 2 weeks one of my headlights went out, I thought it must be a bad headlight blub, so I bought 2 new ones to replace them and only the left side stayed working, could not get the right side to work.

Then top everything the engine blew. This has been a horrible experience lol. So determined to fix my truck I bought a used motor. Truck only has 96k before engine went out, long story short I replaced engine with one that had 60k on it. Got a great deal!

I'm guessing it must be a electrical short problem or something because after reading here and looking on YouTube. I did multiple fixes all with new parts and nothing is working. I'll post a list below of everything I replaced. I'll try to name everything correctly but sorry if I don't say things right.

Things fixed
Used Engine with 60k miles
New Spark Plugs
New Water Pump
New Blower Motor
New Blower motor module switch
New Module for the dash where you press the ac button and fan speed wheel. Not sure the name of this
New Electrical switches the big cube ones in the fuse box and multiple new fuses on the fuse box out of desperation lol that were recommended to change and it was a casual problem for not getting air blown out of ac system
New Ac Recharge juice
New Radiator

I believe that's all I replaced. Any info or ideas would be great! I'm at my end here, if I can't find a fix or solution I'll have to just end up taking a loss and selling the cx9. Might try looking for a car electrical specialist to see if it's a electrical problem but no idea what they are called
