Q: I own a 2004 Buick Rainier CXL, which I absolutely love, but I have been having an intermittent problem with it starting during the past couple of months. When turning the key in the ignition, the security light flashes, the accessories and idiot lights come on, but the engine won’t start. If I play around with the key, the shifter, the remote start, etc., it’ll eventually start. This problem is now happening more frequently.

I’ve had the ignition cylinder replaced ($300) and the starter checked (all good). In looking for solutions on the Internet, I’ve found that a lot of people are having this problem with General Motors cars from 2004-2009. Most of these posts go through all the steps I’ve done (replace ignition, replace key, replace starter, etc.) with no luck, or at best, a temporary fix.

It also looks like there is a company that manufactures a system that will bypass the GM security system and solve the problem. Have you heard of this? Is GM doing anything about this? What should I do? – Karen, e-mail

A: Yes, I have heard of these kits that are available to bypass theft deterrent systems. And I do know that it’s common for ignition cylinders to fail over time. However, before considering bypassing the theft deterrent system, let’s make sure the problem isn’t due to something simple like poor connections at the battery.

GM issued a service bulletin (No. 02-06-04-015A) stating that an intermittent no-start condition could be due to poor battery cable connections. The bulletin reminds technicians that the battery side post threads can be cleaned with a bottoming tap and the battery cable bolt can be replaced separately from the cable to ensure a tight connection. The contact surfaces should be clean of corrosion, too. A quick check of the battery cable connections and the connections at the starter should be made prior to getting a kit to bypass the theft deterrent system.

Q: I’m having trouble with the windshield wipers on my 1994 Chevrolet S-10. They only work on the first delay position and on high; nothing in between those setting works. I’d like to know what the problem might be and if this is something I can fix. – Bernard, Joliet

A: The wiper control module, which is fastened to the wiper motor, is probably the culprit. The wiper motor and module are located under the hood against the firewall and the module is relatively easy to replace.

Q: I need some brake and front end work on my 1994 Oldsmobile Ciera. The problem is I don’t have much money. Can you recommend a shop I can go to that won’t charge much money? – Al, Chicago

A: You might try contacting your local high school or community college to see if they have an automotive program, and if they take in outside work for students to learn from. Other than that, local advertisements or mailers generally feature repair facilities offering discounts and coupons for various types of service.
