Help! My Dodge W300 is blowing nothing but warm air. It feels like summertime inside my truck. What could be wrong?
A vehicle's air conditioning system is supposed to supply cool air and make your driving more enjoyable. However, certain conditions may affect it and distress you as a result. When your truck's AC starts blowing warm air, it is time to check three things that comprise it—the compressor, the refrigerant level, and the electrical system. The compressor is dubbed as the heart of the air conditioning system that allows for the circulation of the refrigerant via a series of stages so that heat inside the vehicle is dispersed. However, when any of the compressor components act up, the usual process of cooling the air is compromised. Meanwhile, a low refrigerant level is something to immediately look into. There could be a leak somewhere, which results in the instant evaporation of the refrigerant so it fails to pass through the stages to produce cool air. On the other hand, the electrical system is made up of fuses, relays, and pressure switches that all work together. Hence, any defect in each of them would cause a problem. Once this happens, you should have an expert diagnose and solve the problem. After all, the AC system is a complicated structure that its evaluation and repair requires ample knowledge.
My brakes lock up whenever I go driving for about an hour. I'm already in my 50s so this really puts pressure on my joints. I know brake problems need to be addressed as soon as possible, but I'm hoping someone could give me pointers as to what to expect. I've met different kinds of mechanics and most of them would always want to take advantage of me.
Clear enough, you should not be driving and putting off the diagnosis of your brake problem for another day since your safety is at stake herein. There are a couple of things to consider during the evaluation such as the caliper piston might already be dragging or the master cylinder itself is already defective. The master cylinder is an entirely functional system responsible for transforming that mechanical force produced when you push on the brake pedals. The seals that comprise the master cylinder help maintain pressure and make sliding into the housing soft and easy. However, if the seals start breaking down, the piston would not be able to return to its original position, thereby causing brake lock up. Since good brakes are essential, it is imperative you have yours checked the soonest possible.
My truck was running fine all day yesterday. However, this morning, I didn't get any spark at all. My son confessed that he took the truck out late last night and got home a bit tipsy. He's not sure though if he was able to turn the headlamps off since he doesn't remember much. Could my battery be drained?
This could be caused by a bad crankshaft position sensor or broken, loose, or corroded wirings from the sensor down to the PCM. You would have to let someone check if your engine uses a separate ignition module or has a distributor and single oil as either of these would likely cause the lack of spark. The spark plug wires also need attention. To check if this is causing the problem, you would have to unplug one of the wires and replace with a screwdriver. Crank the engine and have someone act as a lookout for a spark that would jump from the screwdriver. The lack of spark indicates a problem with the ignition. It is best to seek professional help for immediate resolution.
