Any Canadian Durango owners get the electric fan TSB done?
I found a copy of this TSB, but why does it specify "only for vehicles without daytime running lights"? I have the exact problem they describe but live in Canada so I have DRLs. Why doesn't this bulletin apply to me?
NUMBER: 24-013-01
GROUP: Heating & A/C
DATE: September 28, 2001
SUBJECT:
Warm air blows from panel outlets with A/C on at idle.
OVERVIEW:
This bulletin involves installing an electric cooling fan kit.
MODELS:
1998 - 1999 (DN) Durango
NOTE :THIS BULLETIN APPLIES TO VEHICLES NOT EQUIPPED WITH DAYTIME RUNNING LAMPS.
SYMPTOM/CONDITION:
Some 1998 - 1999 (DN) Durangos may blow warm air out the instrument panel outlets while the A/C is ON in conditions of ambient temperatures exceeding 30°C. (86°F.) and the vehicle not in motion. In conditions of "stop-and-go" traffic or while idling in high ambient temperatures, the A/C high side pressures may exceed the high-pressure switch shut off of 450 - 490 psi. causing the A/C compressor to disengage. The compressor will re-engage once the high side pressure drops below 270 - 330 psi. The root cause of the problem may be related to inadequate airflow through the A/C condenser in high ambient temperatures while the vehicle is not in motion.
DIAGNOSIS:
NOTE :THIS PROCEDURE WILL NOT CORRECT A CONDITION WHERE THE A/C COMPRESSOR DISENGAGES DUE TO EXCESSIVE HIGH SIDE PRESSURE WHILE THE VEHICLE IS IN MOTION. NOR WILL THIS PROCEDURE CORRECT ANY A/C PERFORMANCE COMPLAINT OTHER THAN THE LOSS OF A/C IN "STOP-AND-GO" TRAFFIC OR IDLE CONDITIONS WHILE IN HIGH AMBIENT TEMPERATURES AND HUMIDITY.
Verify A/C system operation by performing an A/C Performance Test. Refer to the 1999 Durango Service Manual (Publication No. 81-370-9116), pages 24-13 through 24-16. If the vehicle passes the A/C performance test as identified in the 1999 Durango Service Manual, yet the customer complains that warm air discharges out the panel ducts with the A/C ON with the vehicle NOT in motion, install the Electric Cooling Fan Kit. If the vehicle did not pass the performance test, repair the vehicle as necessary. This procedure WILL NOT be able to correct the condition.
NOTE UE TO THE ELECTRICAL LOAD REQUIREMENTS OF THE ELECTRIC COOLING FAN, THE 136 AMP GENERATOR IS REQUIRED ON ALL VEHICLES. SOME 1999 MODELS MAY HAVE THE 136 AMP GENERATOR. 1999 MODELS EQUIPPED WITH TRAILER TOW PACKAGE (SALES CODE AHC) ARE EQUIPPED WITH THE 136 AMP GENERATOR. TO ENSURE THAT 1999 MODELS ARE EQUIPPED WITH THE 136 AMP GENERATOR, VERIFY THAT THE PART NUMBER ON THE GENERATOR IS 56028920AA. ALL MODELS NOT EQUIPPED WITH THE 136 AMP GENERATOR MUST USE KIT 05019227AB.
REPAIR PROCEDURE:
Detailed instructions are included in the parts kit. Refer to the instructions for the Repair Procedure.
