Some of the HVAC panel buttons on my '99 LC100 are working intermittently. I ordered a replacement unit from a Pakistan based supplier, Shabar Akbar, a seller of LC parts. The unit was packed well and shipped quickly. My mechanic is familiar with my LC, having previously replaced other parts. He installed the replacement unit, and found the 4WD button and Hazard buttons didn't work, and the AC worked intermittently. My mechanic pulled the Pakistan-sourced unit and replaced my original. To date, I've spent over $400 for the unit, shipping, and repair. When I informed Shabab the unit was defective, he says it isn't defective, but provided me repair instructions and offered replacement parts for the bad switches. Huh? No thanks. I asked Shabab for a refund and return. Shabab informed me the Pakistan government doesn't permit payments to leave the country. Shabab also stated it is 'not fair, or a way forward' for him to pay for return. Shabab is now trying to resell it as is, and have the new buyer send me payment. Communication has become unproductive. Defective units can happen, but I recommend, buy from domestic suppliers that offer refund and return.
