first post here, i tried to do a search and my question wouldnt bring up anything.

the morning temps finally down in the 30's here and i turned the defrost on and only got cold air out of the vents. last week i did notice an odd clicking under the dash on the passenger side. been so busy that i havent investigated what was causing the noise but now suspect this as the problem since the heater worked great last fall/winter.


also my hvac switch only works on number 4 fan speed. any other setting the fan wont work thoughts?

thanks for your time
