My ac/heater blower switch only works on number 4 speed. My friend (who has a '95 850) told me it's the switch that has a problem not the blower. So, I purchased the Climate control switch on ebay for $45, it's the one with cables and sweeping red temperature rotating switch, not the automatic climate adjustment with numbers on the rotating switch. Anyway, I have the climate control now but don't know how to take out the old and install this new one. Hoping somebody out there can help me, an a/c shop is asking $150 for installation. I rather do it myself with a few help from anybody. Is there a code needed if I replace the climate control?
Thanks in advance. Really appreciate it.

Yup your right, after searching the internet I finally realized that it's the resistor that's faulty not the switch. I already bought the climate control so I guess I have to sell it now. Anyway, I got the resistor pack and ac blower so hopefully once I replaced the old ones everything will be normal. Thanks for the note VOBD

Switch is unlikely to be the problem, it's more likely the resisitor pack has failed. This is located in the heater trunking behind the glove box.
