I have a 2008 Jeep Wrangler that has a weird problem with the windshield wipers. When I shut the Jeep off the wipers are tucked down in the normal "park" position, yet most of the time when I return the wipers are up about a third of the way up the windshield. This happens during short stops and overnight in the garage even on days when I don't even use the wipers. It has happened much more in the past two years. Otherwise the wipers act normal. What's going on?
Could your Jeep be "Christine" in disguise? When I read through the Alldata service information covering the front wipers on your vehicle, I was stunned by the system's complex electronics. Yet the wipers provide the exact same functions as older-generation electromechanical systems.
In your vehicle, when the wipers are engaged, the SCM (steering control module) sends a signal to the EMIC (electro-mechanical instrument cluster) over an LIN (local interface network) data buss to the TIPM (totally integrated power module) over the CAN (controller area network) data buss requesting the appropriate wiper and washer system operating modes.
Did you follow all that? The answer is a scan tool to search for DTC fault codes in the front wiper system.
Chrysler did issue a recall on the wiper motor of certain 2008 Jeep Liberty models, but there are no specific recalls or service bulletins on the Wrangler. With that said, I'd try disconnecting and cleaning the wiper motor electrical connector. The motor and connector are located under the cowl at the base of the windshield.
If no fault codes are found and cleaning the connector doesn't help, I'd suggest living with the issue until symptoms are more severe.
I'm having a problem with the ignition, or more specifically the keys, on my 2007 Saturn Vue. The keys are being worn down to the point they no longer work, which forces me to get a new key made. The key does not have a microchip so I got smart and had a local locksmith make several copies costing a few dollars each. My key surplus is now down to one. I fear being stranded, as I travel a lot and I'm never quite sure when a key will finally be worn down and not work. I thought about replacing the ignition with a push button start, but was turned away by the cost. Do you have any suggestions for long-term fixes to this problem?
GM/Saturn service bulletin 06-02-016C dated October 2007 describes how a lack of lubrication in the ignition lock cylinder can lead to wear of metal surfaces and bind the cylinder. I suspect this is what's happened to your vehicle, thus the "fresh" keys are only a Band-Aid fix. The bulletin describes a disassembly/lube process requiring two different lubricants which may fix the problem.
But I can't help but notice that a replacement lock cylinder costs about $70 and takes about 30 minutes to replace. Seems like a simple fix to me.
My 2004 Honda Odyssey was hit about four years ago on the left front and repaired. After the accident it developed a loud, whining sound when I go over 65 or 75 mph. It happens intermittently and can last 20 or more miles, then stop. I have used, you guessed it, duct tape all over the front to stop the wind noise but nothing works.
Have you tried taping down the plastic cowl at the base of the windshield? This was the cause of a loud and annoying whine/buzz that occurred intermittently at highway speed on a Corvette I bought several years ago. Also, if your vehicle is fitted with a roof rack, check for gaps in the rubber inserts for the roof rack crossbars. If the rack was damaged or removed for repair, gaps in these inserts can generate significant noise.
