Hi all....I posted back in March that I completed my intake gasket and spider replacement, so far the old Yukon runs really a lot better and no anti freeze leaks, every thing looks good.
My A/C needed some work (blowing 50 degrees) in instead of purchasing the equipment to do it my self I let a local business purge/charge my unit.
After it was done I was told everything was in spec, but I probably needed to clean out the evap core, and I did. Got a bunch of leaves out, took a tooth brush to it, as best I could. I made a flexible attachment for a vacuum cleaner and vacuumed real good. (see pict)
Then use a garden hose set on stream to wash the core until clear water ran out under the vehicle. This resulted in an increase of blower volume, and it really quieted down a bunch, but it did not get colder.........Until this morning going to Home Depot with the blower on low, 76 degrees out side the temp gauge read 38 degrees, I thought I had it made....but on the return trip It read 60 degrees with blower on high and now 85 outside. I ran thru the controls and all doors appear to be functioning correctly.
So Im not sure what my next move should be ...sounds mechanical, or switch related....Any suggestions would be appreciated.
