PHOENIX -- Last year, 5 Investigates caught Valley companies selling windshield repairs that customers didn't need.

Armed with hidden cameras, 5 Investigates revisited one company that pushed unnecessary repairs one year ago and promised to clean up its act to see if it actually did.

Last year, 5 Investigates made three different trips to Danny's Car Wash at 72nd Street and Shea Boulevard and were subjected each time by sales representatives trying to sell windshield repairs.

"Oh, yeah, any chip will start a crack," one sales rep said at the time.

5 Investigates used an expert windshield repairman, Dennis Riggs, to verify the findings. Riggs said the chipped windshield 5 Investigates used in the report didn't need any repairs.

"Well, I'm actually pressing on the glass, so that if there is a crack, the crack will appear," Riggs said in the 5 Investigates report one year ago. "Since there's nothing there, this will be on there forever and it never will crack."

A Danny's representative agreed the windshield did not need repair after all.

"Those employees were immediately suspended pending investigation," said Danny's official Michael Debord. Debord said Danny's would start its own undercover program to make sure employees do the right thing.

This fall, 5 Investigates decided to check them out again. This time 5 Investigates went to the Danny's at 20th Street and Highland Avenue with the same sports utility vehicle they used last year and with the same old windshield chips.

5 Investigates went in with hidden cameras rolling and asked for an oil change. They got the windshield pitch.

"You have a lot of nicks in your windshield," the sales representative said. "Are you on the freeway a lot? It's a free service, takes about five minutes. We just seal them up before they crack out so you don't have to replace it."

But it's not free. Your insurance company pays for it. The 5 Investigates expert said it may cost $75 or more to fix those chips. And remember, everyone finally agreed last year the windshield didn't need fixing.

5 Investigates asked their expert to inspect the windshield and the old chips a second time.

"There is no crack," Riggs said. "It's just a skid mark, like a chip in the paint. That's all it is."

5 Investigates asked Riggs what he thought of the high-pressure sales approach. "Well, it's deceptive, to be polite," Riggs said.

Once again, 5 Investigates contacted Debord at Danny's. Last year, he said employees had no real motivation to do unnecessary work.

"Not at all," Debord said. "There's no incentive for them to be dishonest."

This year, Debord declined to go on-camera. The company did not want the story to run any longer than necessary.

Yet, he took the time to show the 5 Investigates Danny's own undercover video gear -- gear that is used in the company's "secret shopper" program.

Still, employees once again tried to sell 5 Investigates windshield repairs that they just didn't need.

Debord admitted that the employees are paid on commission, but said that doesn't mean somebody will be dishonest.

"Just remember your windshield chip could be just a chip," 5 Investigates reporter Jon Baird advised viewers. "Which means you don't need to fix it, and your insurance company doesn't need to pay for it."
