Replace? It has to want to change, lol
hyundai it is,
it leaks coolant or core just water blocked, we blow it out with shop air, if clogged inside or if the blend door is stuck closed
you are
barking up the wrong tree for SURE.
the service manual covers that. or do google videos?????????
and is not the same with manual HVAC and climate controls option
the latter can be way more complex and big.
most cars is dash out, not all just most. modern cars dash is way way way too full of JUNK ! toys, and endless stuff. and air bags.
do not work around STS bags until
disabled.
some videos show hacks, do yah?
how many hours labor? really that is it no?
my shop manual shows 39 steps. all is drained coolant and R134
so 80 steps out and in.
10hours hard labor and a ton of stuff fails at the end
shops charge $1500 to $2000 for this job.
steering wheel must be align marked first. or even way more work
