Hi I have a problem with the blower fan, it seems to stay on constantly and I have to disconnect the batteries so I won't have problems, the van doesn't over heat but when I turn it off the temp gets real high. The reserve tank is good and I just replaced the water pump. Well I knew something was gonna happen because I only had the last two channels working the last two. Can you help me and thank you

Suspect faulty heater controler as for temp rise that is common a lot of iron heated up in engine. What I don't understand "I only had the last two channels working the last two"

Sorry I was trying to explain that before this issue. Whenever I tried to turn the **** for the fan speed for heat or a/c what only worked was high and medium and it didn't function on medium low or low.
