1999 HONDA CR-V Power

Overhaul
Note these items when overhauling the blower unit.
. The recirculation contfol motor. the power transistor, the blower motor high relay, and the blower motor can be
replaced without removing the blower unit.
. Betore reassembly, makesurethatthe recirculation control doorand linkage move smoothly without binding.
o After reassembly, make sure the recirculation control motor runs smoothly (se€ page 22-42).
o Make sure that there is no air leakage.

Compressor
Replacement
lf the compressor is marginally operable. run the
engine at idie speed, and let the air conditioner
work for a few minutes. then shut the engine off.
Disconnect the negative cable from the battery.
Recover the refrigerant with a recovery/recycling/
charging station (see page 22-59).
Disconnect the condenser fan connector. Remove
the compressor clutch connector and the wire har-
ness clip from the condenser fan shroud, then dis-
connect the compressor clutch connector. Remove
the mounting bolts and the condenser fan shroud,

discharge lines from the compressor. Plug or cap
the lines immediately after disconnecting them to
avoid moisture and dust contamination,

Loosen the pivot bolt of the idler pulley bracket and
the adiusting bolt, then remove the Ay'C compressor
belt from the pulleys. lf necessary, remove themounting bolts from the left front mount, thenremove the A,/C compressor belt through the gap
between the bodv and the left front mount.

10. Check the idler pulley bearing for play and drag,
and replace it with a new one if it's noisy or has
excessive play or drag.
lnstall in the reverse order of removal. Make note of
the following items,
. lf you're installing a new compressor, drain all the
reJrigerant oil from the removed compressor, and
measure its volume. Subtract the volume of
drained oil trom 130 m/ 14 U3 fl'o2,4.6 lmp'oz);
the result is the amount of oil you should drain
lrom the new compressor (through the suction fit-
trngl.
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat o{ refrigerant oil
before installing them. Be sure to use the right
O-rings for HFC-134a (R-134a) to avoid leakage.
. Use refrigerant oil (SP-10) for R-134a KEIHIN spi-
ral type compressors only.
. To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediately after using the oil, replace the cap
on the container. and seal it to avoid moisture
aDsorprlon.
. Do not spill the refrigerant oil on the vehicle; it
may damage the paint; if the retrigerant oil con-
tacts the Daint, wash it off immediately.
. Adjust the Ay'C compr'essor b€lt (see psge 22-69)
and the power steering pump belt {see section
17t.
. Charge the system (see page 22-611, and test its
performance (see page 22-56]-.

Five-step Troubleshooting
1.
3.
Verify The Complaint
Turn on all the components in the problem circuit to
verify the customer complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the problem area.
Analyze The Schematic
Look up the schematic for the problem circuit.
Determine how the circuit is supposed to work by
tracing the current paths from the power feed
through the circuit components to ground. lf several
circuits fail at the same time, the fuse or ground is a
likely cause,
Based on the symptoms and your understanding of
the circuit operation, identify one or more possible
causes of the problem.
lsolate The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep jn mind that a logical, simple proce-
dure is the key to efficient troubleshooting. Test for
the most likely cause of failure first. Try to make
tests at points that are easily accessible,
Fix The Problem
Once the specific problem is identified, make the
repair. Be sure to use proper tools and safe proce-
dures.
Make Sure The Circuit Works
Turn on all components in the repaired circuit in all
modes to make sure you've fixed the entire prob-
lem. lf the problem was a blown fuse, be sure to
test all of the circuits on the fuse. lvlake sure no new
problems turn up and the original problem does nol
recur.
