    Could be a blown fuse, but fuses don’t blow for no reason. Most likely a faulty blower motor, which is the thing that drives the fan that creates air flow. If the motor shorts out it will blow the fuse. But this could also be a wiring problem or a fault in the control unit





  • I don’t see where they called the mechanic a scammer. But this mechanic is obviously unwilling or unable to diagnose the problem. As you pointed out there will be a code whether the engine light is on or not, so the fact that he said there’s no problem is ridiculous. I agree that a different mechanic who either specializes in these cars or in diagnostics is what OP needs

    To address your original question, the heater core, and also the ac evaporator, is inside a box in the cabin which the blower motor is also attached to. You get heat—or cooling—by having the blower move air across the hot heater core or the cold evaporator. Mounting a core elsewhere would do nothing because it would no longer be integrated into the hvac box or connected to the ducts and vents





  • This could be an injector issue, or something like a crank sensor glitching when it gets hot. But considering how many parts have already been thrown at it, I hate to speculate. Sorry you’ve had no luck with shops so far, but you really need someone who can properly interpret the engine data and/or utilize an oscilloscope to capture the glitch.






  • The brake pedal is only easy to push in the first place because the system uses vacuum assist to reduce the mechanical effort required from the driver. Basically, vacuum from the running engine makes it easier to push the pedal. When you turn off the engine there’s no more vacuum, except what’s stored in a chamber. Next time you park and turn the engine off, pump the brake pedal a couple times and you’ll notice it goes from easy to hard within a couple pumps. That’s what happened after you didn’t drive for a couple days except it just naturally bled off over that time.
