How do I change the heater blower motor?
 

Do I have to remove the dash?

My Hanes manual makes it sound like everything can be done by going through the glove box but, I just don't see how.

My car is a 1989 with A/C too.

It will come out a little tight. you can remove the 10mm bolt on the end of the dash by kick panel and bottom of dash can be pulled out a little to gain more room.

it all depends on if you have A/C or not.no a/c means that the heater core is in the glove box and having a/c usually means it is in the dash....it's a lot easier if it is in the glove box, so i would check there first. can also check under the hood to see if you have 2 heater hoses going to the firewall in the area of your glove box. if so, that is where you will find the core.
