A Whole Bunch of Small Problems

[DodgeV10]

1990 Turbo w./ Auto Trans Issues
1. Blower does not work on Low setting, only med and high, is heater control in dash bad?
2. Drivers side head light does not work on High Beam. Replaced headlight yes. It worked in the summer. Is it a wiring issue from the light back to the high beam switch on the steering column?
3. Radiator hose sucks in when motor is turned off and on start up it blows back up. What's is causing this?
4. No heat blowing out of ducts. Felt the heater core hoses and they are both hot outside the firewall in engine compartment. What to check next?

Thanks for all your inputs. John

1) most likely your blower resistor
2) test voltages at head lamp bulb
3) probably rad cap.
4) check the cable operated valve on the heater hoses to make sure its working (aka cable not popped off etc)

1. agree
2. agree
3. a good starting point, and likely culprit
4. we have no cable control. will be heater vsv failure. I just posted on this in another thread and typing on a smart phone sucks...search the last 3 to5 days.
