Hi I'm having a problem where the air from the HVAC is not switching from face mode defrost mode etc. I replaced the actuator and the problem wasn't fixed. I noticed the cables on the HVAC mode control cable on the driver side is coming loose. I bought the part to replace it but can't seem to find any source that shows how to replace it. When I'm replacing it the new piece can't fit through under the dashboard. Anyone has any idea on how to replace it thanks.
