First of all, I have done a search before posting this, but nothing seems to be directly related to my problem. Anyway...
On my '99 bonnie, the heater fan doesn't turn on. It used to be and intermittant problem; now it almost never works. Doesn't matter if it is set to floor, defrost, vent, etc., and it doesn't matter where the temp **** is.
The problem started a couple years ago, but was intermittant and very rare. Over time the frequency has inscreased to now almost never working. Until recently, it even used to turn on when hitting a big bump (???). Weird.
Any ideas will be GREATLY appreciated. It'* been 10 below here is south dakota the last couple weeks.
