Got a 93 chevy silverado and when u put the ac on max speed the relay behind glove box starts clicking and the speedometer starts jumping. I put a new relay but 2 days later started it again
The power on the control side of the relay may be dropping enough to where it can't keep the load side contacts together . Need to check for voltage drop on the control circuit .
I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 years
