I spent a bit of time at the pick and pull today. I pulled a heater blower motor from a 76 280Z, a 90 honda civic, and an 84 LTD. These three have been the subject of debate on several forums talking about upgrading your heater blower motor. I brought the three assemblies to the counter and hooked up each to a tester (small, handheld, portable device that you hook up to a part as an adjustable power source) As I hooked up each I gave a rating of 1-2-3, and attained this score by the ammount of wind the cage pushed ( I held the assembly "motor side down" with the cage facing towards me to "feel" the airflow from the sides)***do not try this at home serious injury may occur**. 1.The worst was obviously the datsun, very weak in comparison to the other two. 2.Next up was the honda, it had about 20 % more flow in multiple comparisons back and forth with the datsun just to be sure. 3. And finally the LTD, this thing was AMAZING, I could feel the torgue in my hands more so than the other two, and it flowed about 40% better than the honda, I would say this one would be the best of them all by a long shot. My money went to the LTD blower motor assembly. The LTD assembly is mounted under the hood in the passenger side uppermost corner of the engine compartment (easy to get to) but will require a little "custom modifications" to the datsun heater blower "box" to make it fit, but it is possible if you are mechanically inclined and are not scared to do a little cutting and drill new bolt holes. In a previous post I had said " I want to turn on the A/C or heater and have it rearrange my hair" well the LTD is the way to go for this effect hands down. I will post the installation procedure as soon as it is in there. Oh by the way the part was like 5 bucks.
They did have a blower motor already pulled (but already claimed by a customer) from a 96 cadillac that looked REALLY KILLER!!! It is a 150 dollar unit USED !!!! New they are like 300-400 bucks !!! But it had a "pancake" style motor that only stuck out about an inch, but the cage was way to long and would not have fit at all in the datsun box. I didn't get to test this one since the customer had already paid for it and on their way to get it, and I won't be testing one any time soon because it's on the firewall BEHIND THE MOTOR, you have to pull the motor to get it out . Figures though, as soon as you get the right one a better one shows itself, I'm sure I'm not the only one with this affliction....lol
