I just changed the intake gasket, new spark plugs, complete radiator flush, oil change, and temp sensor. But still no heat in cab.
Well either your heater core lines are clogged ore the heater core is just bad

Get the number one piston up, Take the spark plug out the first one on the drivers side.Rotate the engine until the piston reaches TDC before it starts to decend back. U can use a screw driver to put in the spark plug hole.The rotor must point towards the number one spark plug. your local library will have this infor or autozone
SOURCE: My 2000 GMC Jimmy has been blowing cold air. We
airjoc does not have a clue to your problem, I take you want to have warmer air not cooler ac. check the control system, if you have a vacum system tou may have a leak, if it is controlled by voltage, check the control panel and the control box. Also open the hood, place the heater on high but not on any defrost setting preferrably on just the floor setting. Start the engine and see if the ac compressor is running. If it is, the control panel is bad.

On many vehicles the exhaust runs under the oil pan, on others there
may have a cross member in the way, or brackets that will hinder oil
pan removal. These parts need to be removed. The exhaust nuts/bolts
will most likely be rusted. It is best to spray them with penetrating
oil. You can use WD-40, PB Blaster, Deep Creep, or something similar.
After you have sprayed all of the nuts/bolts, let the penetrating oil
soak in for about 10 minutes. Now remove the exhaust pipe that runs
under the oil pan. The catalytic converter may, or may not be in the
piece that you have to remove. If you have to remove a cross member,
simply unbolt it and set it to the side, it is best to mark which side
is the front, as some will only go on one way. Other than that, you should not have to pull the engine at all.
please rate this response and god bless.
