    Have 2 questions for y'all.

    On the firewall (passenger side) underneath the heater fan motor, there are two holes about the size of the heater hoses that are already in thier holes.
    What are these for?

    We thought that it may have been an underdash A/C unit...

    Possibly connected to this issue, there is an extra 3/8th inch hard line above the heater motor.

    Should we just plug these or do they need to go to something?

    Thanks bunches!!

    Haley

    Those are for A/C connections. Works just like the heater hoses, one line in, one line out, going to the A/C compressor.

    Not to be a jerk but, do you guys have an stock A/C unit? Because both cars I have the A/C lines exit and return threw the fan motor hole from a non A/C car. It uses different holes for the heater and the stock non A/C heater holes are pluged. The fan is moved to the inside of the car. If your car has never had A/C the extra heater lines are not drilled but there are small dents to locate them.
