Funstion Test
CAUTION: Bo careful not to damago the moonroof switch
or ths driv6r's dashboard lowsr cover when prying the
3witch out.
NOTE: Check the No. 51 (20 Al fuse in the under-hood
tuse/relay box and No.24 (7.5 A) fuse in the under-dash
fuse/relay box, before testing.
1. Prv the switch out of the driver's dashboard lower

Connect the No. 1 (YELI terminal to body ground
with a jumper wire, then turn the ignition switch ON
(ll). The moonroof should open.
. lf the moonroot opens, check the switch.
. lf the moonroot does not open, check for:
- an open in the YEL wire.
- faulty moonroof open relay.
- faulty moonroof close relay,
- poor ground (G401, G402).- fa u lty open/close switch.
Connect the No. 3 (YELnED) terminal to body ground
with a jumper wire. then turn the ignition switch ON
(ll). The moonroof should close.
. lf the moonroof closes. check the switch.
. lf the moonrool does not close, check for:
- an open in the YEURED or GRN/RED wire'
- faulty moonroof close relaY.
- faulty moonroot oPen relaY.
- faulty tilvclose switch.
Connect the No. 2 (BLU) terminal to body ground with
a jumper wire, then turn the ignition switch oN (ll).
The moonroof should tilt up.
. lf the moonroof tilts up, checkthe switch.
. lf the moonroof does nottilt up, checkfor:
- an open in the BLU wire.
- taulty tilvclose switch
Connect the No. 3 (YEURED) terminal to bodY ground
with a jumper wire, then turn the ignition switch ON
(ll), The moonroof should tilt down.
lf the moonroof does not tilt down, the open/close
relay must be taulty.
Check for continuity to body ground on the No. 4
{BLK}terminal.
There should be continuity.
. lf there is continuity, check the switch
. lf there is no continuity, check for:
- an open in the BLK wire
- poor ground (G401, G402).
