I've had a problem with the engine check light since my Chrysler
Concorde was 3 years old. The stored code is always 33, the air
conditioner circuit even without the A/C on.
The dealer reduced it's frequency a few times, but  it returns in a few
months and  last fall it became a permanent feature of my instrument
display.
Early this year I noticed it was on sooner on light rain misty days. I
noticed a pile of dust stuck to the terminal block on the right side
firewall. I blew the dust  off and the frequency of the check light
coming on reduced very significantly.
Lately it has returned to being more frequent and I've noticed bumpy
roads cause it to come on.
So now I'm wondering which loose connection on that terminal block it is?

Karen,

You're an idiot for going back to that dealership.  The same fool who
couldn't find it the first time likely couldn't the second time either.  Let
me know next time you have 750 bucks to smoke.

This isn't rocket science.

Most parts stores will read your codes for free.  Go do that and post back
what the code is.  Any other conclusion here is a stupid guess.

If a shop can't nail down any problem in your car in 1/2 hour of diagnosis,
they have proven themselves incompetent.  Never return to that shop.

You can reset the code on your own by disconnecting the battery cable for a
few seconds.  You'll need a tool, so hopefully tools don't confuse you.

Good luck, and thanks for financially supporting a bunch of people who would
otherwise be on welfare subsidized by my taxes.

you paid a dealership to fix your ride and yet they did not! you should
ask for a refund
or fix it now for free!
