"From bad to worse" is the pre-qual to the issue at hand.

I finally got the Jeep to have a breathe of life. Took her for a test drive
no fluid issues
power seems ok (dash is still alittle dim)

but there is a definite whoooooshing air sound during acceleration,
a difficulty getting over say 40mph,
and a near over heating issue

When jeeps run they run, when they don't you wanna send em off to cash for clunkers...yay for sodium silicate -quickest way to scare a vehicle into working better than it ever did before!

My theory on these things is not too far off, im sure.

I noticed a while back that I have no heat. The fan blows air but it doesn't get hot. And my AC hasn't worked since last year.
These are two of THE most common issues with heating/cooling in cherokees (plz correct me if im wrong)

Any tips on heater core removal? Im appreciate any help provided

 

Also, i have one of those wal-mart coolant system flush kit "T"s, should I pull the line replace?
