I have very nice 1999 STS with 148,000 miles. I have one code B1343-Air Inlet Door Movement Fault. I get cold air from passenger vents but warmer air from driver's side vents. I've read search results for over 3 hours now only to get more confused. I removed glove box and both kick panels. I found 3 actuators. One under driver's side dash. One behind passenger side kick panel. And one behind driver's side kick panel which controls the rear air. I was told by local mechanic with a scanner that there is one (maybe 2?) more located deeper into the dash towards the firewall (called Air Inlet/Outlet Actuator Right and Air Inlet/Outlet Actuator Left) which is causing my problem. Is this true? How many actuators does my 99STS have?

------------------
the Air Inlet Door is the "RECIRCULATE door -
it allows - or restricts outside air
to be mixed with inside "conditioned" air -
there are two "MIX" DOORS -
#1 is the driver side - #2 is the passenger side -
these control the temperature of the air -
there is a "MODE" door -
this controls WHERE the air blows from -
---------------------
I get cold air from passenger vents
but warmer air from driver's side vents
if this happens when cold A/C is selected -
most common cause is a slightly low charge of freon -
I'll check the freon charge today as basscatt suggested. EcSTSatic, is the air inlet door actuator the one on the passenger side? And, after I replace it, will B1343 go off by itself or do I need to remove battery cables or something to reset?
I'm 99.9% sure that's it. It's really hard to get the screws out. The back one in particular. Takes a lot of patience. Once I replaced it, I think I just had to clear the code on the dash controls and it went away for good.
I had freon charged. Yes, it was low. I'm getting cold air out of every vent now. I changed actuator on passenger side and it's fixed also. B1343 went away. I strongly recommend using a swivel socket to get back screw out. I did some extra exploring while under there to help others out.
B1340-refers to actuator in panel above driver's feet.
B1341-refers to actuator behind driver's side kick plate.
B1343-refers to passenger side actuator (glove box and kick plate removal)
I did this by unplugging each actuator, one at a time, and seeing which code came up.
Disregard reply #7. Wrong info!
B1341-refers to actuator just to the left once you get glove box removed. Easy access.
B1343-refers to passenger side actuator (glove box and kick plate removal). It's sort of hidden in the back right. Hard to access. Takes a little time and patience to remove the 2 screws.

I have the mode door problem. Where is it? Blower blowing great just no airflow through vents. Ranger had a thread about this I think but the pics are no longer there . Any help would be appreciated.
I have a 2001 seville STS. The rear shock absorbers seem to work ok, but look pretty bad. There are quite some little cracks in the rubber and the lower part is greasy.
Is it necessary to replace them? Or do they always look like this?

Hi folks.
Can anyone tell me how to determine which fuel injector is throwing my P119 code? Or how to tell whether a fuel injector is bad? (I've got a 94 SLS with the Northstar motor.) Thanks for any help.
I am hoping someone can tell me how to tell which shocks are on my 1998 STS. I saw a pic of the electronic air shocks and they had an electrical connection on the top in between the 3 upper shock bolts that hold it on. looking under the hood mine didn't have a connection with wires going there...
Hi I have a 95 Seville SLS and I recently disconnected my fpr from the fuel rail and reinstalled but I seen once I removed it that there were 2 small o rings on the nipple that goes in the rail first. My problem is with one small o ring out and with both in my fuel pressure regulator is leaking...
