1999 chevy c 3500 crew cab.
5.7L V8
Repair done prior = replaced lower intake manifold gasket at 140,000
Repair this problem = replaced distributer cap/button
check vacuum lines and PCV
question = truck(5.7 Vortec) has an incredible amount of vacuum. Difficult
to just remove oil cap..air is rushing through breather duct into carb, valve
over through PCV...... Engine has a high idle and is running rough...I was
told to replace intake manifold gasket, not sure if this could be the lower
intake gasket again... Truck has been an awesome truck, which i bought
new... i have allot of miles on engine and sure allot more to go once this
issue is resolved... Can you help me? Any help would be appreciated....
Thank you for your time......
KK:
Yes, i would have to agree. Probably the lower intake gaskets have gone
out, or the upper intake plenum has burned through somewhere. Inspect
the upper during replacement of the lower gaskets.

Question: How do i remove cover to blower motor which quit working?
Question: How do i remove cover to blower motor which quit working?
Answer: The easiest way to access the blower motor on your vehicle is
to remove the glove box. There a couple small bolts at the hinge on the
bottom and a release near the compartment back. The lower kick panel
trim needs to be removed as well, which is the same type of screw. The
blower motor will be right there behind the glove box area, and usually
has 5 small 7/32 head screws holding it in place. Disconnect the
electrical connector and replace with a new blower motor. You might
want to check the blower resistor which is located near the blower
motor. If the motor isn't working, the resistor could be the cause.
