Some buses too stuffy, but this bus is super
cold

Another DM 3500? 
Previously, many months back. the natural
themostat on SBS 2749L of 335 was also spoilt. It's really
very cold in the morning, but in the afternoon, it's
acceptable. Summore I take the bus in the morning at around 6:30am,
I literally shivered. The BC had to activate the wipers because the
windscreen was also misty and he couldn't see anything. Since then,
I believed the bus went for repair and the aircon was back to
normal.
