GMC SONOMA BLOWER MOTOR PROBLEM

1995 GMC Sonoma • 103,000 miles

4 cyl, 5 spd. If I have the cruise on it runs for a while, then the idiot light (brake) comes on and the speedometer drops to 0 and the a/c or heat blower motor shuts off, the cruise shuts down. If you wait a few it all comes back if it wants to, sometimes I turn the heater switch off and on and it works. Can't seem to find problem. Any suggestions? I ran a ground to body, but not to frame or dash metal still does it. HHEELLPP

My husband's truck is doing the same thing and I ran across this trying to find an answer. It's going to start being too cold to not have the heat working right!

Not sure this will help with the cruise and everything, but my husband had someone tell him their S10 had the same problem with the heat and it's the resistor. Just thought I'd throw that out there.
