What are the symptoms of "A/C Defroster system isn't working"? No fan? Only
blows out defrost ducts?

Have you had a look under the van? Where exactly in the "front" was he
tugging? the grille area, underneath, where?

He

This question really can't be answered accurately unless you provide more
info.

Is there

There are refrigerant lines that lead to the condenser in front of the
radiator, and they may accessible from underneath, but probably not from the
grille.

If there is foul play involved, it wouldn't be the first time a shop had
made its own problems. But like I said, it's hard to make a judgement
without more detailed info.

My A/C Defroster system isn't working.

My van recently had an oil change and I saw the mechanic
beneath and in front of the van, just left of center, tugging
something a couple of times using some force.

Is there something like a hose that is in front of the van just
left of center that has to do with the A/C Defroster system
that could have been damaged by the mechanic?

There are numerous electrical and mechanical failures which
could result in an A/C problem or a defroster problem.  They
include ignition switch failures, defroster control failures,
relay failures, vacuum line breaks, stuck air doors, blown
fuses, refrigerant loss, A/C compressor failure, drive belt
failure, etc.

It's easy to learn what the mechanic was doing:  Go back to
the oil change shop, describe what you saw to the manager,
and ask for an explanation.

With no description of the symptoms other than "isn't working"
no one in the newsgroup can begin to help solve the problem.

Good luck.

If its a full service garage and not a lube joint sounds like he was
checking
front end components for slop.

if you took it to Midas, the guys probably screwing you.
I took my 2004 Ford E250 van in for an oil change. I wasn't watching
closely but what I saw from the customer's lounge worried me. What's
more is that now the A/C Defroster system isn't working.
The van went on the lift. The waste oil drum went under the engine. The
mechanic drops the oil filter into the funnel of the waste oil drum,
moves to the right and then undoes the oil plug. When he went back to
the front of the van, just left of center, he tugged something. He
tugged a couple of times and appeared to be using some force. The
question is, did he sabotage the A/C Defroster system? Is there
something like a hose that is in front of the van, on the left as you
look at it or just left of center that has to do with the A/C Defroster?
