First car radio volume goes all the way up and sometimes stops working, 2 weeks later car would not start was a short in wire of starter, Now the heater and ac lights are on, but the heater or a/c not working it. This is after having rebuilt transmission in September2024 then October had Brakes, rotors front, and back, radiator replaced, sparkplugs replaced tune-up. Oil change, rack and pinion tie-rods replaced. Then 2 weeks later control arms and bushings were replaced in November and then car would not start in December was short in starter wire. Now 1week later no heat or A/C. Lights are on but not working. I also bought transmission mount because the engine is moving. But not put on yet. Have spent 9000 dollars on this car. What could this be. Thank you. P.S Replaced Battery and Alternator in Sept 2023. Cannot do anymore. Please Help.

Can you tell me if you can hear the blower motor working or when the HVAC system is on there is no noise? If there is no noise, you could have a blower motor that is not working. This guide can help you test the system; you can just have a blower motor that has gone out, which is common.

Also, does the blower not work in all speed positions? Check out the images (below). Please upload videos in your response of any problems so we can see what to help you with.
