Hey scotty I have an 99 toyota camry 2.2 I'm having a/c issues well my blower motor burned out I replace it with a brand new blower... Now the issue I'm having sometimes the motor blower kicks in and sometimes it won't! I'll have to drive and it'll kick and but soon as I turn my car off and turn back on boom nothing... Could the motor blower be defective?
