91 Ford F150 Larado XL, 302 V8, pw, pl, cruise, 60,000mi.
My issue is, when I am running my defrosters, and the compressor engages, my charging guage drops below the normal range, and when it disengages, it returns to the normal range. My question is two fold. Why or what is making it do this, and why is it necessary for the a/c compressor to run while the defrosters are running. I am mechanically challenged but it appears something may be astray. Can I unplug the compressor temporarily to keep it from cycling. Thank you in advance for any advice.
have the same problem?
