Wahoo funny thing when I took my 40 burb apart it had three heaters. None of them look stock, I just thought the heaters were an aftermarket or dealer op. Anyway I had one heater under the drivers seat, small pancake thing, one heater above the steering column, little tiny thing about 6 inches diameter,only blew hot air to drivers side winsheild, and one heater by passenger fire wall, just blowing air into the front part of burb, the right side defroster wasn't hooked up, but the dash has the vents for it. under the hood looked like a plumbing nightmare. heater hose running over the engine and up and down both inner fenders. Guy that might know is Barry Weeks. I looked in the owners manuel and service manuel and they don't even mention a heater. Weird
