The EVIC gremlin returns
Hi All,

just under a year ago I had this problem, the EVIC would drop out "----" instead of figures, windows wouldn't open, no light flash on lock, no auto courtesy lights etc. etc.

Had loads of advice about self checking the EVIC, BCM, ECM even TCM but it turned out to be none of those. Discovered, by accident, a fractured water temperature sensor. Replaced that and all has been O.K. until the last couple of weeks, when I had all the old symptoms again.

Thought, I know what that is, bought (8.50=$13) and fitted a replacement sensor. No such luck. Guessed it must be down to the AZC system somehow, as just before it happened the Aircon would kick in at inappropriate times.

Ran the self-check on the AZC, came up with fault codes 12, 22,29, 30 32, 52 & 56, most of which are down to blend doors. Replaced the blend doors with a JGC kit (I see Jeep have copied his design, but Chrysler UK only sell it in the housing. Robbing b******s!).

Did all the resets and recalibration procedures. A.O.K. Zero errors, fault code "0", on self-check. Drove round a bit and after a few miles, out drops the EVIC etc. etc. Self check on AZC then gives "20" error, which is listed as "AI (Recirc) door travel too large".

Question is, where is the "AI" door? Is it something I could 'fix' myself?

Please don't suggest I go to the local Jeep garage, they couldn't find their arses when standing naked in a well lit room!

Thanks in advance.

Looks like the text of a new movie..........The EVIC gremlin returns...........:lol:
The recirculation door sits inside the HVAC housing and when i'm not wrong right above the blower motor. To replace a broken door you would have to tear down the dash. You can see the door when you just take out the blower motor.

Just behind the glove box, on the bottom of the hvac box, lower right. You'll see it clear as day round piece three screws holding it in

You can see it when you pull off the glove box. It sits behind a grate but you can't get at much without tearing things apart.

Re: The EVIC gremlin returns
Your jeep being a right hand drive, i'm not 100% sure about the location. On LH drive vehicles, you can easily remove the blower motor from the underside of the HVAC housing when you look up at the passenger side foot well. 3 Screws indeed and 1 connector. No need to open the glove box, because there you only find the drivers side blend door actuator.
But as said before, on RH driven jeeps it could be different.
