It was 100 deg F outside the other day and the air temp coming out of the
vent was only 85. I bought the truck recently (base 2003 Tacoma 4 cylinder) and don't know the history of the A/C maintenance.
When servicing the A/C, can you just add more refrigerant? or does the system need to be vacuumed and then refrigerant added?
I'm pretty mechanical, and think I could take on this project if I get a proper set of gauges. Or is this something best left to the professional.
I do want to do it right, and not cut corners.
Any advice would be appreciated.
