I was driving my Dodge B250 going home when I felt that it suddenly changed its shifting. From its usual 28, it now shifts at around 40. It feels smooth and I don't hear any noise or leaks, but I'm just curious as to what could be causing this. What's could it be?
This sudden shift is probably due to your vehicle's throttle pressure cable that has slipped or came out of adjustment. This cable serves as the connector between the throttle body and the transmission. It is responsible for telling the valve body inside the transmission on the position of the throttle. When this happens, all you need to do is to have the cable checked and adjusted by an expert or a technician. You may also choose to do this on your own, but you would need to find an online resource to do this successfully.
The battery of my trusty Dodge Van B250 continuously drains even when it is not running. Changing the battery is not an option for me because I cannot afford it at the moment. I would like to know how I can fix this problem without having to purchase and replace it with a new one. What's happening with my vehicle? Should I bring it to the car repair shop already?
It looks like there is something draining your vehicle's battery even when it is in idle mode. What you can do is to check it with a 12 volts test light. Make sure to keep all your doors closed when you perform this test. Disconnect the hood light if necessary. Take off one of the battery terminal ends, and run the test light from the battery post to the cable end. If it lights up, you need to start pulling fuses one by one until it goes out. If it finally goes out, the circuit is causing the problem. If it doesn't, then you have no choice but to replace your battery because it can't hold a charge.
I wonder why air only blows through the defroster duct of my vehicle. Also, the air-conditioning blows outside air, and the compressor does not engage. I am planning to skip the repair shop and just do the repair by myself. I was thinking of inspecting the refrigerant pressure and recharging it. Should I pursue my plans?
Your problem is likely caused by a vacuum leak. Inspect the vacuum system, and if the compressor is not running, install a set of gauges and read the system pressure. If it is 100 to 110 PSI, then it is normal. When checking for leaks, make sure that it has Freon. You can also use some A/C dye and a black light to make it easier for you to check for leaks. If your vacuum is positive for leaks, it is important to bring it immediately to the car repair shop and have it repaired or replaced. Once neglected, it may lead to worse problems in your vehicle.
