REPAIR
NOTE: If heated front screen: 2 electrical
multiplug connectors are located under
the decker [cowl] panel. To access release
decker panel.
Remove
1.Remove windscreen wiper arms.
See WIPERS
AND WASHERS, Repair, wiper arms -
windscreen.
2.Remove rear view mirror and stickers from
glass.
3.Remove'A'post finishers.
4.Fit protective cover over dash panel and apply
masking tape to protect'A'posts.
5.Ease one end of bottom finisher away from
glass, pull to disengage finisher flange and
remove.
6.Lift lip of LH'A'post finisher and release sealing
strip along its length, pull to disengage finisher
flange from glass and remove.7.Remove RH'A'post finisher.
8.Remove header finisher.
9.Apply masking tape to protect paint finish around
glass.
10.Prepare cutting wire in handle'A'.Bend end of
wire to handle and tape over end.
11.Force cutting wire through sealer from inside and
100mm (3 7/8 in) from a top corner. Use a
needle if necessary to make a pilot hole.
12.Attach handle'B'.Allow 200mm (7 7/8 in) of wire
between handles, tape over end of wire.
13. With an assistant on the inside:Wedge the
tube of the handle'A'between glass and body
flange 100mm (3 7/8 in) ahead of hole in sealer.
14. From the outside:Carefully cut sealer from
flange using a straight pull away from the glass.
Continue in 100mm (3 7/8 in) steps around the
glass, use a sawing action at the corners.
CAUTION: Along the bottom edge, great
care must be taken to cut up to the 2
supports, positions indicated on the
obscuration band (See item 18).
15.Remove handle'B', withdraw the cutting wire
and insert it through the sealer between the
supports. Refit handle'B'.

FAULT DIAGNOSIS REFRIGERATION SYSTEM FAULTS
For any refrigeration system to function properly all
components must be in good working order. The unit
cooling cycle and the relationship between air
discharge temperature and ambient temperature and
the pressures at the compressor can help to
determine proper operation of the system.
The length of any cooling cycle is determined by such
factors as ambient temperature and humidity,
thermostat setting, compressor speed and air leakage
into the cooled area, etc. With these factors constant,
any sudden increase in the length of the cooling cycle
would be indicative of abnormal operation of the air
conditioner.
The low and high side pressures at the compressor
will vary with changing ambient temperature, humidity,
in-car temperature and altitude.
The following items should be checked before
operating the system:
1.Compressor drive belt tension.
2.Compressor magnetic clutch operation.
3.Condenser fan operation.
4.Condenser fins, dirt will cause poor cooling and
higher operating temperatures.The following conditions should be checked after
operating the system for several minutes:
1.All high pressure lines and components should
be hot to the touch.
2.All low pressure lines should be cool to the
touch.
3.Inlet and outlet temperatures at the receiver/drier
should be at the same temperature (warm). Any
very noticeable temperature difference indicates
a blocked receiver/drier.
4.Heavy frost on the inlet to the expansion valve
may indicate a defective valve or moisture in the
system.
5.Evaporation air temperature will vary with
ambient temperature and humidity. As humidity
increases the outlet temperature will be higher.
