Hi all,
I am wondering if anyone else has experienced this problem:
With the speed control set, as it needs to add throttle to maintain speed on
a hill, it seems like there is a loss of vacuum and the air control for the
heat-A/C blower seems to switch to defrost.. as the speed is attained, and
throttle is backed off, the blower switches back to whatever setting it was
on before..
Recently it's also started acting funny when engine breaking. After about 5
seconds of engine breaking, it will suddenly become much more efficient,
almost like I've kicked on a jake brake. I'm guessing this to be a vacuum
problem as well, thinking perhaps there is a vacuum controlled diaphragm or
something that's taking a while to close..
This is a y2k QC 4.7 5spd 4x4 slt+
Getting ready to take it in to the dealer for the seat belt bolt recall, the
above issues, backup lights that sometimes refuse to come on, and an issue
where occasionally neither remote transmitter will lock/unlock the truck,
and then 10 minutes later they work fine. Thought maybe if someone had been
through these vacuum issues I could point them in the right direction...
