97 grand caravan: Electrical problems? Heater blower dead
hey everyone,
My caravan has a big issue and I don't know if it's even fixable or not?
It's winter here in Canada, and my heater died. I'm in need of a fix for this so I can get home then move to another place.
I found that on the panel with the AC, rear defrost, wiper button etc,
the lights are always flashing. When i first got this vehicle, the fan would sometimes make a squeal noise for a bit when I tuned it but after a little bit it was ok.
but eventually the heater started to just shut off when i changed gears from park to reverse or drive an such and it especially would when I pressed rear defrost button. (rear defrost doesn't seem to do anything else) The heater would not work (no effect from switch)
but it would eventually come back on after a while.
Now though, it never comes back on. I checked the relay by putting in one of the same type/numbers on it and the fuse is ok. didn't help. moreover there was a 60A fuse in it when it should be 40A.
Has something fried? could it be the motor or resistor block or motor itself?
any help would be very appreciated!
EDIT: The heater blower came on today again this morning, but when i shut off engine and start again, it was gone.
No idea what this is??

Ditto. The resistor block connector is know to overheat and break connection. On your van it's under the hood bolted to the passenger side firewall. http://www.originalmechanic.com/2013...-resistor.html

Thanks for the help! I got the van repaired at a shop. apperantly the wiring was all fried, so it had to be fixed and the burned areas bypassed. after that, everything worked again even some other little glitches I was having. cost me 250$ in the end but i guess thats not too bad to have this issue repaired. So I got home in time and all is good so far!

Heat is good. That said, I hope it was more than the usual fried harness leading to the resistor block. Replacement harnesses pigtails are available for $25 and very easy to replace. I think there's even a YouTube how to video on the subject. Anyway, you've got heat at the right time of the year - a big plus.
