I've done some research here on swapping out my heater core (getting fogged windows on interior with heat on real bad). When I remove the heater core, here are a few questions I have not been able to get answers to from other threads-
1- Passenger Airbag- Does the dash-mounted passenger airbag have to come out, or does this stay mounted in the upper dash, and this doesn't have to be removed? (I know wiring harnesses will most likely need to be unclipped, etc, and disco the battery before working on this... yeah... got that, but wanted to know if I had remove this airbag or not).
2- A/C Evaporator- While I have everything opened up and dash removed, I want to swap the evaporator core too (seen lots of comments about how they suck from the factory, and currently A/C doesn't work but did last month, so hoping to fix any possible leak with new evap core for cheap money)- Do this headache of a job only once. To completely remove the heater box from the firewall, I know I need to disconnect the heater core from the coolant lines, and the A/C lines from the evaporator- BUT
, from what I gather as a semi-conscious human being, I need to get the A/C system property emptied as to reclaim the R132a legally before I crack open the A/C lines. No where have I heard anyone mention this step in any threads- Can someone validate this for me as well? I assume the evaporator has R132a in it, unless there is something I am missing and it's filled with magic or something else??
3- Once I button everything back up, is is possible for me to get the A/C system back in working order on my own with a rental of a vacuum pump, and a few cans of R132a, or does the pressurization process HAVE
to be done with all the equipment at a service center?
Any other quick helpful comments appreciated to help make this crummy job any easier would be great!!
