Default A/C Heat issues?

and to add to the grow list of issues my car is having today I noticed that the heat is not as hot as it should be.

I usually have to keep the cabin set between 70-72 (if it's colder outside) and can feel the warm air blowing out of the vents. Tonight I had it set to 74, no AC on, and it was blowing cold air out. 74 has typically been a pretty warm setting so I cranked it up to 78 which is usually an oven and that setting felt more like the normal 74.

My water pump had to be replaced two months ago, the bluetooth is having issues, and now it appears the heater is having issues as well.

Any advice, other than to continually take it into the dealer to have repairs made?

Default What kind of BT issues?

My connection has been full of static so I asked the dealer to check it out yesterday during the 5k service. He said everything checked out fine and blamed it on my iPhone, but nothing was written on the service paperwork so I assume nobody even looked at it and he was just lying.

A few days ago the phone would show connected but the car didn't. It was like this for about a day and then it has been working fine since then.

I also need to have a rear speaker checked out. I listen to my music loud but not full blast or anything too extreme. Sounds like it may be blown.

Very frustrating to have problem after problem but I still love the damn car.

I have had similar issues with my 2004 Acura TL when the outside temperature is around the 50s. It seems like the sensor cannot figure out how to compensate for a moderate outside temperature, so it blows cold air.

On mine, if you put the temperature setting to the highest level, heat will come out. Then I back it down to 70-72, and what was cold air is now warm. Kind of like rebooting a computer when it is stuck in a loop.

Hope this helps.
