Q: How to remove the receiver-drier in a Hyundai Elantra's air conditioning system?A: For 2007 and later models, remove the condenser. Use a hex wrench to remove the bottom cap from the A/C Accumulator and pull out the desiccant. Replace the desiccant, and install a new O-ring and air conditioner oil. Install new O-rings on the refrigerant line fittings and lubricate them.
