Can anyone help me?
I changed the spark plugs today and once I finished the job, I started the car and noticed the AC was blowing hot air.
Turned the temp setting to low and it blows cold air but only on low setting. Was wondering since I had the negative disconnected for a while when changing spark plugs that this has caused a computer glitch?
Checked everywhere around the engine to see if I knocked any plugs off but all is OK.
Any suggestions would be much appreciated

Thanks

It's all good. Worked it out. Decided to pull the fuses for the HVAC's in the fuse box located under the driver side or in the US passenger side. Started the car and wham bam the AC is working correctly. Don't know if it was a coincidence or not but I'll take that win ;)

Cheers
