I have 2 questions, both unrelated.

1. It sounds like the fan is continuously running and as the engine speeds up the fan speeds us. It sounds sort of like a rumbling... Is this caused by a faulty fan relay? How do I replace and cost?

2. The AC quit working on both sides of the vehicle. It is equipped with the dual climate control system. I have seen where some people have issues with warm air coming out one side and cold on the other, but this doesn't seem to be the same. I can adjust the air warmer, but the AC never gets cold. The code put out does say blend door range too small. Also compressor does come on and hoses do get cold, just no cold air inside.. What’s the repair and cost?

Thanks much!

I'm not sure about the fan but as far as the A/C goes I have a 99 with the same dual climate. Mine put out heat but no A/C and I had to replace the condenser box. I took it to a mechanic friend and he charged less that $200 I believe but it involves having to take the whole dash out as well as buying the new part. The best way to test it is to put a dye in to see where the leak is. Thats how I found out on mine.
