Bob - question on blower motor

[DanEC]

Bob - I'm kind of confused on the blower motor. As it is furnished, I belive it is simply an off/on affair handled by a two-pole toggle switch. But, there are various references in the manual about a 2-speed and even 3-speed heater unit being furnished and some discussion about wiring in a separate switch to control the additional speeds.

I assume with just the off/on switch it will run on high in the on position. Typically heater motor lower speeds are operated by a resister or resister bank. There is a discussion about wiring in a separate 3 pole switch but I'm unclear on the wiring. Is the idea to disassemble the heater and splice a switch to the internal wiring for the motor? There is just a single wire coming out of the motor as delivered. Seems strange the motor and wiring internal to the unit would be set up for multiple speed operation but there isn't any plug and play capability on the outside of the unit. Is there a further discussion or description of this process somewhere?

Maybe I'm missing something all to obvious again.

Thanks

Dan

When we prep the unit, we "hide" the low and medium speed wires inside the case. Just connect the remaining wire to the toggle switch to have a single-speed blower.

If you're obsessed with having the other speeds, you'll have to pull the heater out, disassemble it to access the other wires, and use a different switch mounted underneath the dash. I've got the old ones here somewhere.

OK - that fits in with the instructions in the manual. I was looking for something that said you have to open up the heater. Guess I better do this before installing the dash and filling the cooling system.

Thanks

Dan, thanks for asking that question. I was reading that in the manual and was confused as well but haven't gotten that far yet.

Bob, I also read that the blower doesn't put out a tremendous amount of air or heat. Based on that, are the multiple speeds worth the effort?

Thanks,

Kevin

Kevin - a good question (I suspect the answer will be no). With me it's kind of - it's an modification that is there to perform - do I do so just for the sake and self-satisfaction of having done it or move on(?).

Hi Dan,

I understand that completely - I'm the same way. I recently installed an in-dash navigation system in our family car. It had an optional wire that can be hooked up to the speedometer to track you while in tunnels/lost signal areas. Hooking up that wire meant removing the entire instrument panel - a lot of work. And who needs GPS in a tunnel? Well, I couldn't help myself and hooked it up anyway

In this case, I'd just like to know more before proceeding.

Keep us posted on your progress.

Believe me, if you need to turn on the heater, the only setting you need is "high." On a late October day/evening here in the NE, the high setting its equivilent to having an ol' hound dog pant on your ankles, the others you won't feel at all.

Jim,

Great analogy, that's what I thought about the heater.

I have the heater in my car, but if I were to drive my car for any real distance, in cold weather, I would get one of those cigar-lighter-powered electric blankets and put it over me. That, along with the soft top, that now fits pretty darn well, and my side curtains, would make it quite snuggly. But, I have no desire to drive the Cobra in anything but nice weather....

Another consideration besides just output is noise. If the fan is irritating noisy when running on high I may want to install the switch and accept a little less heat for less noise. Patrick/Jim - can you comment on noise?

No noise. That is a "non-issue."

Thanks - having installed undercar exhaust on my car I tend to forgot the rest of you probably can't hear anything over your sidepipes anyway.

Thanks Dan, I appreciate the detail.
