Need blower or electroinc brain for blower Mod# mast 300-750-120/60 samoi-a-n s/n# mast 210406-181

No fuse for speed control. Does it run at one speed regardless of the switch setting?

I have found a couple of places that appear to have what you are looking for. They are both in the US and priced in dollars which may be good or bad depending where you are.

Good Luck.

The air switch has a clear tube that goes between the button and the control switch. I would pull it off at the button and blow into the line. you should easily be able to activate the air switch by blowing. and you should audibly hear it click each time you blos on the hose. if no cluick, the air switch is bad. bost blower motors dont have a reset button but I have seen some that do. I am not familiar with the brand you have. I dont know how mechanically inclined you are but you can pull the blower motor apart, or atleast see if it is frozen up maybe from sitting. Check the power core between the control pack and the blower motor as well. good luck. Tim

How do I install a new antenna on my GMC 05 2500 Sierra. I have to replace the base because it broke off. I've taken the dash off. But cannot seem to fish wire through the firewall.

If the mast is broken then you can unscrew the top part of the aerial, turn on the radio and pull till the whole mast and perlon come out, then get your new mast and feed it into the aerial and turn the radio off, this should pull the mast and perlon in. other wise buy a new arial, you will need to get under the wheel arch and remove the plastic cover, the aerial will be held up with a screw.

Its probably the blower itself.

could be rust build up on the magnito

It looks like you've got DDRII memory. According to Crucial http://crucial.com you can place up to 2GB of memory on your machine. (1GB in each slot) If you're unsure, remove one of your existing memory sticks to verify that it's DDRII.

hmmm ...ok...we need to diagnose the brain...check fuses and relays ..anything related to a/c heat blower motor and power to head unit /blower resistor blower.... and advise..also... get code check to see if a soft code stored telling us the cause..... advise

You access the ariel via the left hand wheel arch.
1. Remove left wheel mud guard. It is held in with a bunch of press studs which can be difficult to remove. I found pulling on the plastic mud guard whilst turning the screw helped.
2. unbolt the electric ariel assembly. There is an earth strap that needs to be unscrewed as well.
You should be able to get the ariel out far enough to work on it.
3. Remove chrome plated nut to top end of mast tube.
4. With great anger and force, remove the dead ariel and drive cable from the mast.
It's difficult to get the mast to work unless it's earthed properly.
5. Get you hand inside the wall and remove the ariel face plate. Swear if you have to.
6. Put the ariel mast assembly back into the wall and hook it all up minus the new ariel.
7. Switch your radio on, then put the new ariel into the mast. Gears facing the rear of the car. Switch the radio off, it should retract. If not you may need to push it in a little further.
8. Remove the ariel mast again and slip the chrome nut to top end of mast tube and tighten securely.
9. Ask the spouse to close up whilst you have a beer.
