Why is it every time I press the brake while the A/C is on it sounds like a belt comes off (like a klunk sound) and the heat comes on untill I turn it off and back back on than it blows cold again.
I know the heater core is cracked because I could see and smell fumes coming out. But what's up with the a/c?
I just bought my truck about amonth ago with 130k miles on it, it's gonna need a new transmission cause it's not wanting to go into gear normally. I have replaced the track bar and did a one over tune up. I've already put around 10k miles on it.
Any help will help, thanks guys!
