The front windshield wipers will not work at all.

Yes it is for the front motor and I fixed it by chance. I took off the steering wheel housing and checked all connections, all seemed snug but after that they started working. Hopefully this will solve this issue. There is no information out there about wiper motors on this style of Tahoe. I almost took it to the shop, which I almost never do unless I am exhausted of options.

good deal,maybe switch in column had a gremlin,and you scared it away,and not come back.
