Tech Tip: No or Insufficient Cooling Output in Mercedes-Benz C-Class

If an owner of a 2004 C 240 Sedan complains of no or insufficient cooling output, it could be caused by the refrigerant line, whose inner coating has come loose in the flexible section of the hose, causing constriction.

Stronghold for 1234yf is Crumbling – Part II

In this installment of a two-part editorial from R744.com, high refrigerant costs, the need for new plants and pending patent issues put the use of HFC-1234yf more and more into doubt.

Diagnosing A/C Systems with Automatic Climate Control

Diagnosis is often the biggest challenge, especially if the cause of a no-cooling problem is not obvious. Is it the refrigeration circuit, an electrical problem or a control issue?

Supporters of R744 in Mobile A/C Systems Express Problems with 1234yf Refrigerant

The growing reluctance over 1234yf has now led its own proponents and Original Equipment Manufacturers (OEMs) to dreadfully search for a system solution that would enable the use of the refrigerant, no matter what the system cost and efficiency implications

Directions: The Impact of HF0-1234yf on Service Shops

According to the new refrigerant’s developers, there are chemical differences between HFO-1234yf and the current R-134a system. As a shop owner, you’ll need to learn the Safety, Equipment and Charging Issues surrounding this new refrigerant.

Tech Feature: New Refrigerant Change May Not Be a ‘SNAP’

The introduction of HFO-1234yf in vehicle A/C systems in the U.S. could be a few years away. However, it is plausible that some (dealership technicians and collision repairers) may see HFO-1234yf systems by late 2011 and early 2012, as European models begin the R-134a phase-out and make their way across the pond. (R-134a is to be completely phased out of new European systems by 2017.)

Lexus Tech Tip: A/C Condenser Fan Relay Corrosion on 1998-2000 LX 470s

Some 1998-2000 model year LX 470 vehicles may have a condition in which the A/C condenser fan continues to run after the ignition is turned off due to corrosion in the relay connector. A repair kit (P/N 88840-60070) consisting of a new relay and sealant has been made available to correct this concern.

Toyota: Insufficient Cabin Cooling

Some 2001-’04 Sequoia and 2000-’04 Tundra vehicles may exhibit a condition where the air conditioning system does not sufficiently cool the cabin. Adjustment of the water control valve is necessary to correct the condition. 2. Inspect the clearance between the water control valve lever and the lever stop. If the lever does not contact the

Tech Tip: Kia A/C Compressor Bracket Replacement

Some 2002-’05 Sedona (GQ) vehicles may exhibit a humming noise and vibration when the A/C is turned on. To address this condition, replace the A/C compressor bracket with P/N 1K52Y 15810FFF.

Tech Tip: Honda Pilot’s Compressor Clutch Has Taken Off

No A/C compressor clutch. The scan tool says A/C off and A/C switch off. There is no air out of the front vents, but the blower motor operates and changes speeds with the front switch.
