Easy first check:
Inspect the check-valves (disc looking valves in-line) the can go bad & kill vac pressure;
easy replacement, although the newer ones I've seen are much wider than OEM; more a cylinder shape.
Just make sure you orient it properly when replacing.
Good time to check 'em all...
"hi" setting actually bypasses the relay.
Kinda' common; check the purple wire on the blower;
follow it down the P/S firewall & pull the wire up
the connector gets corroded;clean it up & you should have full blast again!
HTH!

Did a few pieces w/ the Harbor Freight unit; not bad (upper & lower radiator hard pipes & some other odds & ends)
I bought an apt. sized oven off C/L to coat in; the main thing is prep/clean/mask.
make sure part are clean & preheat 'em possible.
The only pain is moving the parts into the oven...
This sounds like a defective mfg. suit; you need start at the very beginning of the chain (retail store) & work your way up.
Document everything & keep a record of all damages/ rect's
look around for an atty to handle products liability cases (most law schools have a clinic or referral service)...
Check the Purple wire coming off the connector on the blower motor, its the main power to the blower; trace it down the corner of the passenger side cowl area by blower, down the door post area
wire/conn. gets corroded.
wiggle it around & fan see if fan comes on.
lots of posts on fix
(No relays...
Yep, put in new servos for door locks & had to replace P/ window switch also,
D/S wouldn't work w/o P/S plugged in; I guess they are wired in series.
