The only negative about the process was the shipping cost vs delivery time. The cost was steep for the amount of time it took to arrive.

I had a terrible experience with GM…
I had a terrible experience with GM Parts Giant and would strongly advise others to avoid them.
Their customer service is essentially nonexistent. Communication is slow, unhelpful, and they do not take responsibility when issues arise. In my case, I never even received the item I ordered. I was notified that it was lost in transit and later confirmed it was being returned to the sender—yet they still refused to issue a refund.
Despite multiple follow-ups and providing proof, they continued to delay and avoid resolving the issue. It feels like they are more interested in keeping your money than actually helping their customers.
If you value your time, money, and peace of mind, buy from literally any other retailer. This was one of the worst purchasing experiences I’ve had.

Great pricing with good availability of parts. Genuine GM part was set & functioning in a low mileage 2004 Chevrolet Avalanche. This was a complete blower motor kit, with all after market motors a complete failure. Good shipping as well!
