Just completed heater upgrade on my YJ

Hey all. I just completed the blazer heater blower upgrade on my 1990 YJ and for the money, its the best upgrade out there. The correct part number is siemens PM102. Dont get the 105. Its too long. The 102 bolted right up and required no shimming. The only thing that was even remotely time consuming was making the hole in the firewall approx. three and a quarter inches. No big deal though. I used a scroll saw and a dremmel tool with a high speed cutting bit. It looks like a factory job and WHAT A DIFFERENCE!!! This blower motor puts out as much hot air on low as the original one did on high! I advise anyone to do this upgrade. If you need any help, let me know. Oh yeah the motor was about 20 bucks at Autozone and guaranteed for life. Another thing, if you plan on doing this swap, take the little foam seal from around your original motor and stretch it around the new one. Its tight but it will fit. This will help it seal to the firewall. then once its installed, its a good idea to run some Black silicone around it.

I dont have any pics but you can do a search on the net. Just type in "Jeep heater upgrade". One guy has some pics posted on the subject. One tells you to buy the PM 105 but you actually need the 102. Or at least thats what I discovered after researching. Its really easy to do and you dont have to be a master mechanic to do this. Trust me, its well worth it and simple.
